I've got a bug where the fog of war isn't properly being removed when I walk into it. This prevents me from targeting any of the enemies inside. I attached an image displaying the issue. The arrow is pointing at the current active character, and I still can't see anything around him.
This occurred in the Turn-based mode.
I've only encountered this once so far.
Edit: Was able to beat the encounter by using targeted abilities against the enemies in the turn-order list, but I couldn't get the area to light up at all.
