I run modded Isaac and for some reason when I get trigger it, it changes the look but without the horns. I have looked within the files and only had one mod that makes an edit to it, but I don't have it enabled. The rest are all costume sprites for other characters.

I do however have my suspicions that Wardrobe+ might be messing with something.

Anyway, hopefully someone can enlighten me as to what's going on and how to fix it.
