I'm making an item pack, but for some reason it just crashes, and modvalidator finds no errors. Someone please help, here is the file:
Did you make sure that the icons aren't what's crashing it? You could check that by trying to substitute all icons used by your mod with ones from the core game - if it stops crashing then it's a sprite issue, if it doesn't then it's the code.
Maybe. I don't have time to get through this thing today so I just proposed doing what tends to help fix the issue.
