Guild Wars 2

Arah explorable – Jotun path
Was killing the Ooze boss in the first part of the dungeon, and after killing one of the silver spawns, it spawned two lesser oozes right in the wall. Were unable to continue the dungeon, because shots were obstructed and the mobs were immune.

You don’t have to kill the lesser ones to progress.

Well the dungeon didn’t progress for us. The pointer remained on the first stone with the NPC telling us it was guarded by a monster that devours undead or something (assuming this is the slime boss he’s talking about).

Oh, huh. I guess it must have just bugged out favourably for us then, because the same thing happened for us (slime randomly spazzed into the wall with some stray spider adds) but the dungeon continued after killing the “main” one. And the add died/waypoint disappeared when we triggered the detonator on the aeroplane after the crystal bosses.
