Entered the Blood-Slick Pit, killed the stuff that spawned, then killed the Colossus, but the quest didn’t complete or progress in anyway. Left the Blood-Slick Pit and came back, Colossus spawned again, killed it again, still no progress. Logged out, logged back in, returned to the Blood-Slick Pit, nothing happened. Abandoned the quest, picked it back up, entered the Blood-Slick Pit, nothing spawned. Abandoned again, picked it back up, again there were no spawns, but there were no two Colossus in the corner, but not attackable. Kind of stuck on this quest line.
