Maybe it's because Angel's graphics are only a single prop, and changed the name of the png file.
For example, in Angel's smelting, Blast furnace base was named just blast-furnace.png, now it's named blast-furnace-base.png.
I tried changing the code and it said that the scale of the .png file is bigger than it can handle.
Idk if someone would understand my explanation if you need to clarify something just type it here.
Edit: If you get Artisanal reskins for Angels then maybe the crash could stop.
