Noticed a weird little glitch! When I was making my custom assets I was baffled that the engine wasn't loading the Eyes13 I made. I realized the reason is because it always loads the amount of parts you have for Skin00, and Skin00 is missing the Eyes13 file. Maybe you left it out when compiling the zip? When I just duplicated another eye and named it that, it made all the Eyes13s come back for every other skin too.
