I was playing with my co-op buddy when we entered Mordus' basement in Driftwood and after solving the puzzle there and getting into combat with skeletons we realized my character (Beast) was not entered into combat like the rest of the party and instead could wander around using skills and attacking the enemy while outside of combat and killed everyone without even getting dragged into turn-based combat. We also shortly after realized that I (still Beast) could not talk to any member of the party or any NPCs and was unable to take damage or get status effects other than self-buffs, for example I would not get poisoned while walking over poison. No idea what could've caused this glitch, the last thing we can think of was I picked up a key as combat started and before entering the building I was talking to NPCs just fine. Reloading to an old save (we've been using quick-saves so this real save was 4 hours back) fixed it and Beast was able to talk again. We had no quicksave available to load just before combat so I cannot tell if it glitched before the combat started. Just figured I'd try to report the glitch, hopefully this long post is in the right spot!
