Current Work In progress, good fun. The Umbrella one, if this is the intended solution then it's a brilliant.
I assume the clappy clapple is a backroute.
looking forward to finishing the ones I haven't gotten yet.
There's a high variance in difficulty

Are the green checks disappearing altogether, or turning orange?

If they're disappearing altogether: That suggests the userdata.nxsv file is either being corrupted, or outright erased (or potentially, not loaded properly).
Whereas if they're turning orange: That suggests NL thinks the level files have been modified since you solved them.

Can you change your script to attempt to cleanly close NL? Might be worth a try at least.

Thank you for the guide WillLem. Now I am still waiting for green checks to disappear again, but it did not happen recently.

One thing I thought about : I set up a process on my machine that kills NL regularly, to prevent me from playing too much  This process brutally does "kill NeoLemmix.exe" if it is running late at night for instance.

Maybe the green checks issue could happen if the kill occurs when the game is accessing userdata.nxsv for instance ? I could not reproduce it though, no matter when I try to manually kill NeoLemmix.exe, my green checks survive.

OK, solved updated versions again.

RE: Your hint, still not sure which level it refers to, but it seems to me to imply an Oh Noer - that would refer to a blocker in a different state, i.e. in the process of exploding. If so, I suppose that must relate to The Lemming Ledger, but I can't see why that would be beneficial unless the explosion is also creating a path that was previously inaccessible.

My thoughts on my solutions, so you can see my working, as it were:

R1:

Spoiler

This is a solution I haven't tried before for The Lemming Ledger. From very early on, I always thought that thin piece of steel half way up the cliff face must serve a purpose and I believed that purpose was for a miner to mine backwards towards therefore closing off any way back. Until now though, I couldn't see a way to put it into practice - the lemmings were too close together and once I started bashing, a couple would always pass by before the miner tunnel was deep enough. What I've done here is extremely fiddly and precise though, which leads me to believe it's still a backroute but hopefully closer to your intended solution.

R3:

Spoiler

When you said I was close a couple of attempts ago, I took that to mean that my initial move of blocking the builder and immediately digging him out so that two lemmings go in opposite directions is correct. That would also tie into the title of Reverse the Polarity! This time I did need the additional digger because if the miner had continued on his trajectory, he would have landed on the platform and therefore, the newly added trap.

No worries! I understand it can be frustrating to spend time on fixing your levels only to watch people backroute them again - not intentionally, by the way, I want to stress that. I just try to find what seems like the most optimal, logical solution to my mind, which I guess doesn't always necessarily coincide with the author's intent. @Guigui's suggestions for fixing your Sour 2 level sound good, I'd definitely try to implement some of those!

On a more general note, I'd just add (from watching other authors fix my backroutes) that some other good tips for enforcing an intended solution are adding strategically placed steel elements, making terrain elements one-way (left, right, up or down arrows, depending on your purposes), reducing the amount of available terrain in key spots, locking release rate lower and adding more traps (both of which Guigui mentioned). I get that not all authors enjoy fixing backroutes, but if it's seen as part of the level creation process maybe it can be an enjoyable challenge in itself: outwitting the solvers, and making them dance to your tune!

Sorry if I'm being dense, but is your hint supposed to be for R1 or R3, since both levels contain blockers?

I'm also sorry to cause you frustration; it might be better to admit that I'm simply just not on your wavelength for these two levels - it can happen. Mostly I am (even if it takes a while to get there a la Outside the Box 2), which is why I like your levels and persist with them, but I think my repeated attempts and failures at The Oubliette also showed that occasionally I just ain't gonna get there!

Nevertheless, I'll take a look at your updated levels, if only to check I can't backroute them for your peace of mind Not actually asking for any hints, it would just be good to know whether I've ever been on the right track with The Lemming Ledger, or whether every single attempt has been far from what you intended!

Quote from: WillLem on November 30, 2025, 04:10:18 AMIn theory, if we wanted to go down this route, could I run a server from a Raspberry Pi 5 just for hosting the necessary files? I have one that I've not really been using much, and it would be fun to learn about file hosting, especially if it might help to make engine updates much easier for everyone.

You probably could, but hosting it on your own home internet connection is not the best idea. Firstly - in order for people to be able to access it, you need to at least slightly open up your network. If you aren't careful, this can create major security risks. Secondly - you may not have a static IP address, and/or may have a shared IP address. The former makes this setup difficult, while the latter makes it impossible. Thirdly - is your internet connection (and where applicable, power) fast enough, reliable enough, and always-on enough for the job?

The better way to go would be to get a paid plan from a cheap hosting provider. You definitely want one that supports at least PHP (and probably offers a MySQL database too - you might not need it right away, but you likely will want one eventually if you do much with the web hosting). If you want to get a bit more in-depth and more DIY-y, look into a VPS provider.

Where the Pi could come in handy for this is as a development / testing environment. Install a web server on that and use that for development and testing; while opening up a device like this on your home network to the wider internet can quickly get risky, doing so simply between two of your own devices is pretty safe. As a bonus - if you can manage to set this up as such, you most likely will have learnt (at least most of) the skills you need to be able to use a VPS rather than a managed host.

I'd suggest using Debian or Ubuntu (or a fork thereof) as your OS, preferably a version with no "desktop environment" (ie: your Pi won't have a GUI like Windows; if you attach it to a screen, you'll just see a DOS-like prompt. This has two benefits - firstly, that's going to be far more in line with how using a VPS will be; and secondly, far less overhead being used for the GUI, meaning all the device's power can be used for the web server and other servers you might choose to run on it). I'd actually advise - set up a "LAMP" setup first and play around with it a bit; this is for the sake of the understanding it'll give you of the underlying workings. Then when you're comfortable with that, nuke the whole thing (server-wise; you can definitely backup and keep any sites you were working on - and if you don't want to erase the working server just in case, it's a Pi, just get a second microSD), and this time, look into VirtualMin and install that; VirtualMin makes it much more convenient to do a lot of management tasks. For reference: The Lemmings Forums server is a VirtualMin setup (on a DigitalOcean VPS, but as mentioned, I'm planning to move it... it's just a matter of actually picking one, and getting it done).

EDIT: I should clarify that "no GUI on the Pi itself" doesn't mean you're stuck with command line for every web development task you do. You'll use the command line a lot while initially configuring the server (especially the non-VirtualMin one), and might need to occasionally pop out the command line after that (probably remotely via an SSH connection, rather than physically using a keyboard and screen attached to the Pi), but you're mostly going to be working with GUI tools - you're just going to be using those GUI tools on your PC, not on the Pi itself, then uploading your work to the Pi (or, the web server / VPS, once your site is ready to go live).

Quote from: namida on November 30, 2025, 01:15:09 AMOne thought that comes to mind is having a "user-gfx" folder, with the same structure. If a file is present in that folder (or the appropriate subfolder) it's used; if not, the default one is used.

The Lemmini family uses this very same system via a "mods" folder. This setup works nicely to preserve user gfx for sure, but it's not without its issues. For example, let's say we needed to add a new icon to levelinfo_icons.png. We can drop the new one into the default location, but if the user has a modded copy in their user-gfx folder, they'll be missing the added icon and might never know.

Having said that, if updates ever went online and were done on a file-by-file basis, I suppose one way around this would be for the engine to detect the presence (or not) of an updated file in the user-gfx directory, and alert the user when they first run the updated program.

In theory, if we wanted to go down this route, is it possible to run a server from a Raspberry Pi 5 just for hosting the necessary files? I have one that I've not really been using much, and it would be fun to learn about file hosting, especially if it might help to make engine updates much easier for everyone.

(Apologies this has gone way off topic btw, please do split this off into its own topic).

My apologies for the bitterness, that was uncalled for I need to learn to step back from the keyboard for a bit when I get frustrated.

I appreciate the kind words from you both. And Guigui, that is indeed essentially the intended solution for Sour 2. Thank you SO MUCH for your suggestions, genuinely. I'll be sure to try them out tomorrow and see what works.
