Unplayable Character Bug

Beat Act 1 on Witch. Beat the first Act 2 Boss Hyena guy. Went to the base to travel to next zone and got the following error

Exception
Attempted to resume current action with an invalid skill: 1073741824 object:
Metadata/Monsters/EtchedBeetles/SmallEtchedBettleArmoured@32

Game proceeds to freeze and then crash.

Not feeling the desire to restart with a new class/character at this point.
