Bug Report: Custom skins not working, even with modified .xml

[Salted-Beef]

i used a custom skin mod for this and pressing any note crashes the game. I've added the proper frozen and worried animations into the .xml and .png but doing anything other than the idle animation with the custom character crashes the game. I don't know why.

Edit: It seems that this problem only occurs if i turn on anti spam. I still have no clue why this happens. Also, when a song ends, the game crashes.

Mic'd up engine requires the sprite sheet to be exported as charling type for it to work
