The hooded Dark Forest shirt is bugged so that when it is "used" to create a technique and applied to armor, all of your character's hair then clips through the hood. When the shirt is used normally there are no issues, this appears to only happen when the technique (costume effect) is applied to an armor piece.

We solved the clipping issue by simply getting character appearance change tokens and making our characters bald, but if there's a way to avoid that in the future, that'd probably be best.
