[BUG][ED] Error when clicking Ruler to access skill mask guides

[Flopsy]

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.

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.
