Blood Furnace super buggy and you can brick your run

[BatuKhan]

Blood Furnace has all sorts of pathing issues. NPCs jumping up into the air, and your party gets stuck in various places around the instance, unable to follow you or move in any way. You can also become completely stuck when you get to Broggok. The Fel Orcs in the cages can aggro through the bars and run out before you've pulled the lever. If you do this, then when you do pull the lever and it gets to a cage that is already empty, you brick your run, as the game never registers those fel orcs as dead. Thus, Broggok never comes out and you cannot progress. I managed to do it by using gm commands to teleport beyond the gate, but I couldn't fight Broggok as he remained in a non-active state.
