[Bug] No sprite during fight

I have a bug with a fighting animation. I have a Dragon Disciple, with Robe of the Good Archmagi, and it seems that some moves have no sprite.

Only happened when i had the evil archmagi robe, if i remember right.
Could be related to the combat animations of the archmagi robe model (all 3 variants have the same model).
