Olroth Dies Without Reviving

Olroth sometimes dies in phase 1 without ever reviving, he drops his loot as normal but then you're stuck in the arena since the arena red portal is up and you can't port out since you're still considered inside a boss battle.

Only way out is to wait like 10-15 minutes logged out for the instance to disappear so you're put back into your hideout.

Plz fix.
