Wizard BB stuck after fighting

Description

After one of the fights, my Wizard BB was stuck in an animation loop, checking out his grimoire (basically, an animation where he was holding up and down his grimoire). During this time, it was impossible to issue any commands to this particular team member. It was only after some time that he broke out of the animation loop and followed the party. However, the wizard was getting stuck on each combat encounter since.

Repro steps:

Didn't try to reproduce this bug yet, but it would be about it:

1) Go to Dyrford dungeons

2) Keep fighting the guards

3) Observe if any of the team members get stuck in animation loops

Expected behaviour

I expected my characters to be fully functional in the game, rather than stuck doing things.

There seem to be some animation-related null reference exceptions.

Sorry, no save game (I've accidentally overwritten it with something else).
