In the crystal seam the Gladiator Fight with Lauzkduul the Novice is bugged.
After agreeing to fight him you don't teleport into the arena and the NPC doesn't move. Also if you head into the arena it will trigger the Fight Script and you'll be locked in without any means of exit, without the NPC not even entering.
Also Yielding does not unlock the chamber. So you're just kinda stuck lol.
