Aside from the quartermaster re-spawn which is broken, I shuffled my guild (Titans of War) into BWL via UBRS (which did not require attunement using this method). We did a practice run on Razorgore and wiped. We ALL released and did a soft reset for 30minutes (we hung out in BRM waiting for the non existent Quartermaster).
Once we returned into BWL, one by one whenever we zoned into BWL the gate was down, Razorgore was running around with all of the spawns chain one shotting anyone who came into the zone. Again, we did a soft reset and this did not fix the issue. It seemed to just chain loop and restart infinitely. You would zone in, gate was closed, no aggro, gate opens all adds + Razoregore re-appear and one shot you then run wildly around Razorgore's lair.
