Just started the enchanter’s lair in Legend ; a patrol spawned close to the beginning and was stuck. Could hear the noise of it walking, but it was just standing there in the corridor going away from the room with the two cages and the sarcophagus whose lid can be pushed.
First time this happened and no idea how to reproduce nor what caused it. Playing with one friend and two bots ; I was Zealot, friend was Shade, bots were Footknight and Battle Wizard. Someone tried to join but left before joining as we entered the room.
