I was doing a jelly king run today, joined at depth 12.. went to basil... changed gear and then we went into arena on D14.
We started on the first room, all fine untill i fought a mechaknight near the fence in the south. I hit attack with my sword a few times and suddenly Im outside the room, beneath the fence. The others in the party finished the room but the fence remained closed and I couldnt continue. I tried closing the game in task manager and rejoining, but I was still below the fence.

I tried doing a Contact Support but all I see is a white screen unfortunately. I recommend others not to fight near the fence lol. I lost 10 energy :S
