I was doing the Tomb of Idris Dungeon when I fell through the floor and was stuck on an invisible ground underneath my teammates but I was still able to interact with them and enemies providing they didn't walk up any levels. I also wasn't able to pick up items, I missed out on 2 sets of Manticore seals
After I completed the dungeon and left the party I made my way back to the campfire with Acolyte Brimn and he was obviously not up against a wall like he usually is. Just thought I should point these things out.
