Was running Castle Thorn with three other players. All was going well, we were cleaning up, until we came to the stairs leading to the area with Lady Thorn. A player and an enemy Senche Raht both got clipped through the stairs, and stuck under them. They could not port out, we tried to force the Boss Fight to force them out of the stairs/wall, but couldn't even open the door due to "stuck in combat". We even tried kicking the player, which we really didn't want to do, they were great, and even that didn't work. We all had to just abandon the Dungeon. Yes, I have submitted a bug report in-game
