Bodach Left Arena Phase 2

Bug Report ID: #191889224

Finished the orb phase on Bodach, boss reappeared but then decided I wasn't worth killing. Moving around can get the boss HP bar to reappear, but never becomes visible/target-able, or attack me.

Edit: I can't even log out to leave the instance. My character is still in the boss room, unable to leave until my instance times out.
