Seems to be a completion bug here. Ran it 3 different times this week and floor 2 only gave a 60% or so score. Had a group of 5 so we sent those who did not complete back to scout for routes we may have missed. Couldn’t find a way to access but there are mobs up on the sides that are unreachable but targetable/attackable.
Is part of the map missing? seems to be a common issue - few threads about it in general it seems.
