fotm, hammer zone, cage bugged
Same here: near the very end of the fight I was put in the northern cage and I couldn’t attack it or anything. I ended up not getting to loot the chest and had to move on.
Same happened to me in one of my runs, and actually 3 out of 4 members (one had disconnected earlier so we continued with 4) got trapped in same cage. Like rest, I did not manage to loot the chest that spawned shortly after our imprisonment, lost the tokens.
Though the fact I disconnected in the next map and lost the overall progress was way more frustrating.
