I feel like there may be some unintended things happening in Sleepers Tomb Contested. Mobs like, I believe his name is Bibl Gnost, or similar, on the first floor, right wing, by the tall book cases. He applies his debuffs to every player in the zone, not just the encounter he is engaged with. Also, Mezarim the Queen on the third floor, the ooze puddles she spawns during the fight, they can remain for upto hours afterward, so if she has been killed often there can be patches of ooze all over the floor for ages. These arent huge problems but by their nature I am assuming they also arent intended to be happening, so just a heads up.
