Doing the quest to take out some local bandits, I got into tactical battle, killed the leader with my sovereign, and then attacked the bandit wolf with my summoned familiar. The tactical battle then looped, with the familiar and wolf attacking each other over and over, doing 2 points of damage each time, but never ending the battle.
Here's a video of the looping, showing the endless battle.
Here's the debug.err, showing a lot of these errors:
Debug Message: ANIMATION CORE LEAK: IAnimationController 343A6EB0 leaked with 2 refs
I finally broke out of the tactical battle (I can't remember exactly what I did to do that, but escape didn't work), and here's a saved game after that point.
