can't leave boss arena.

Defeated the boss and can't leave the arena on rustbowl map. Clicking on "arena" and it does not port outside the boss room. Seems like it is blocked by some invisible wall that would prevent players from leaving the zone while the boss is alive but in my scenario it is dead. Apparently this is a common issue and is around since 0.1.

Relog did not help.
