Hey dex, loving the Cake tileset. You timed this release well to co-incide with the recent Contest rule which actually expects us to make a birthday cake style level.

It's a shame there is no flame to put on top of the candles, it would be a nice touch to this tileset if this were to be added. Especially seeing as the exit has lit candles on it 

I did search other tilesets in the editor but nothing really fit, the closest match I got was the lanterns in the Proxima persia set but they were a little too big I found.

Otherwise this tileset is top quality and will make a great quality R2 contest level for me 

OK, figured it out.

The rulers were being added as 24bit RGB images with no alpha channel. The actual fix is to normalize them to 32bit ARGB during loading. I'll release an Editor hotfix shortly.

Fixed in NLEditor commit bafe87c.

Yeah, for some reason the rulers all have to have some alpha value (transparent/semitransparent pixels) in the .png image. I still haven't fathomed this one.

The attached rulers zip should fix all of the errors reported in the OP. Let me know if you're still seeing terrain/object/whatever pieces when you switch to rulers though, that definitely shouldn't be happening and I've been unable to reproduce the behaviour.

Great job Dexter. Will those be included in the style manager in NL, or do I have to download them manually ?

@Guigui
Technically I one-shot the level but I took full advantage of NL's replay editing. I roughly compressed the crowd using permanent skills first, then I adjusted the timing by advancing the lemmings' assignments a few frames if they poked out ahead or delaying them a few frames if they fell behind.

So... if I had played this on WinLems instead, it would have taken me way more time.

QuoteRC/experimental NL builds aren't allowed, only the stable version of NL!

Not sure that this note is needed anymore.

Well, WillLem sometimes has experimental versions of the Community edition.
This should not change physics, but in the case something is unintentionally broken there, this note still covers that edge case. 
But in the vast majority of cases it should not matter anymore.

Hi Flopsy,

A temporary workaround until the issue is fixed...
I've noticed that by replacing the native "rulers" folder with the one from SuperLemmix, it works perfectly for me.

So when I open the editor and click Rulers for the first time. This error pops up, I have to click ignore twice to clear it.

The first 9 slots in the editor piece display show the skill masks up to the glider one and the remaining 11 slots still shows terrain pieces (or whatever you were on prior to clicking Rulers).

Clearing the error will cause the ruler pieces to display in all slots again but with 2 pieces not displaying correctly.

The Ruler pieces still display but the vertical line one is blank for me and clicking this re-produces the error message again.
The horizontal line one is also not displaying correctly and is a bunch of dots, this also produces the error if clicked on.

18 - R1 requires 1 hatch, 1 exit, no steel or OWA and no interactable objects but R2 requires you to remake an official level with a new solution but there is probably none if any which satisfy R1. Probably be proved wrong here but I'm willing to bet this is not going to be a fun set regardless.

Original levels with one trapdoor, one exit, no steel, no one-way wall and no other objects (except for water on the bottom, which is allowed in contest 18's rules):

(Levels in parentheses have purely decorative steel; you'd have to ask the contest organiser whether this is okay)
<Levels in angle brackets have a purely decorative interactive object; same applies>

Fun 1, 2, 3, 4, 5, (6), 7, 8, (12), 13, 14, 16, 19, <20>, 22, 25, <26>, <(30)>
Tricky 1, 2, 3, 6, 7, (8), (11), 12, 14, 15, 16, (17), 18, 19, 21, 22, (23), 24, <(25)>, 30
Taxing 3, 10, 11, <(12)>, 14, 15, 20, (23), (24), 25, <(27)>, 29, 30
Mayhem 4, <7>, 11, <13>, 17, (19), 20, 21, 22, <(24)>

I may have missed some or marked some wrongly, but the point stands, there are a lot of eligible levels, and that's just from L1 (contest 18 states that ONML, Genesis, Holiday and other official levels are also eligible). Probably doesn't matter since this is still a hard set to do and it's unlikely anyone will pick it, but I just wanted to make things clear so that people know the possibility is there
