I dunno the trigger for this, but sometimes combat gets stuck on one of my companions' turns. When it occurs that companion can move around indefinitely and use skills but they don't do anything. And that companion cannot end the turn - Space or button do not work.
The only thing that helps is save/reload. However once I got this bug twice in a row after trying to help Paladin Cork I had to quit the game and reopen it. So maybe it's a memory leak bug, cuz I've been playing it for quite a while before the bug appeared.
