I find chaotic to be strange, like after level 3 I easily breezed through levels and now I'm on level 11

Thanks kaywhyn! I think I did it the intended way based on what you said in your hint but you can download my replay I put in the post above just to see.

I just tried the pack last night and I'm already on chaotic 3 Death Chamber which has stumped me for now. It's a great pack! And very good for someone like me who's never beaten a level pack or even the original lemmings for that matter.. kinda embarrassing actually..
Edit: So, I solved Chaotic 3 but I think this may be a backroute but I'm not positive... and I want to know!

Actually yes, I do know what pack it would be. I don't think it really matters which one it is but it's one I never really played so I guess I can get rid of it and get it back if I feel like playing it. So I'll get rid of the pack, and then see if the error still occurs.
Edit: I got rid of all the packs I never played and I might get them back at a later date, but the error is still happening. So clearly I haven't gotten rid of the corrupted PNG file yet.
Edit 2: So I think I found the corrupted file. It's in my own in development pack Shmolems. It's a rank graphic specifically so I'll just get rid of it and re-create it later. I find it fun to make graphics for my pack anyway so no trouble. If the error still occurs, I'll look for another corrupted file.
Edit 3: So getting rid of the rank graphic worked! Everything works fine now. Thanks for your help!

So it worked. But then after I went onto neolemmix and tried some levels to see if the error was still there. I went out of neolemmix then later went back to it but when it tried to use the neolemmix application an error message appeared saying "Not a valid PNG file." What do you mean not a valid PNG file? Last time I checked, neolemmix isn't supposed to be an image.

Ohhhhh that's probably why I'll get the new styles folder and see if it works

I'm experiencing an error in which every time I try to access a level an error message occurs saying "Invalid pointer operation" not sure if this is because of neolemmix or just something else on my computer in general. But this means I can't play any levels on the new version or even access my own from the editor. I'll put a pic of the error in post just need to get a screenshot

In terraria, I've made it to the final boss of the calamity mod! Her name is Supreme Calamitas and she is sooooooooooo hard! Seriously, I haven't done a single point of damage to her..
Edit: Actually, my record on her now is getting her down to 20% hp.

I agree with you. Most open, giving you way more than you need levels are definitely not my thing. I do find them boring and just a waste of a level. (I also find it satisfying to finish a level with every skill used) and if you're interested I posted some pictures of some of my levels on my Shmolems: For Real This Time topic on the in development board.

Yeah those methods could totally work for me to! All of my levels give you EXACTLY the amount you need to solve them.

Wow I wasn't expecting such a huge wave of response! I think the first thing I'll try is playing other levels. Though sometimes an idea just randomly comes

Thanks everyone! I have plenty of ideas for my moderate ranking which includes levels that are focused around one "trick" with a skill/skills. My ranking simple is hard to think of ideas because they are mainly just little puzzles. My advanced ranking might be a bit difficult to make because I'm going to put the theme for moderate and the theme for simple together so it will be puzzles that also include some kind of trick.

So recently I've been struggling to get level ideas for my in development pack (Shmolems) and I'm curious to know how some people here get their ideas because some of you have created packs with hundreds of levels and my pack is only going to have 40 but I'm still struggling to find ideas. So how do you do it?

I played a few levels and I'm liking it so far! In fact, It gave me an idea for level I'm going to make for my level pack! I remember when you mentioned that your levels were small, but I didn't expect that small! (Not a bad thing tho)

Now I have another question about how big should a graphic for the play, level select, quit panels be?
