Getting errors and game shutdown. Cannibal archers animation 23

error is:
"Arts/Models/MONSTERS/CrazedCannibalPicts/CrazedCannibalPict:Male/animations/Bow/rig.ast" ; Faled to uncompress animation 23

Happened a lot of times since last patch, making me lose my maps and any drops on ground. If i log back in it just immediately pop up with same error and shuts game down.
