Hi, lately I've taken to running the Atoll of Immolation public dungeon (accessed from The Deadlands portals) daily for a chance at those Annihilarch's Chosen motifs from the last boss.
I noticed this first on U39 PTS but thought it was just something weird on my end since it was my first time trying stuff out there, but there are invisible enemies in this dungeon now and the load screens seem to take much longer than before.
The load screens also seem to be the same for other people in the zone as you can see in this video I recorded this morning; another player joins me in the dungeon and appears to load in at the same time once we start going through portals to progress (that might be relevant, idk). Both load screens were almost two minutes!
As for the invisible enemies, I can still kill them with AOE effects and my pets seem to have no trouble finding them.
