In the village invaded by goblins, near the Owlbear cave, a problem occured after the fight started, where my party was in a house and goblins on the roof of that house. They could shoot me through the roof, but I couldn't aim at them the same way. The roof being invisible and impossible to zoom in or out on, I was unable to determine whether there was a hole in the roof or it was simply a bug.
Also, after casting the spell "mirror image" and then taking a rest (at which point the spell isn't active anymore), the cleric is constantly followed by three shields around her, as if the spell was still active.
