This quest, when taken, creates a journal entry for the 'Blue Sun Tenements Infestation', but the Royal Apartments are never called the Blue Sun Tenements anywhere else. The quest description names the location appropriately.
When I entered, not the first person on this reset to have done so, no enemies spawned. I couldn't find a completion trigger anywhere, either, so I had to abandon the quest.

Fixed quest journal entry.
Hopefully fixed quest for next reset, let me know otherwise.
Can confirm, tried to go do this quest today [1-23-2019] and the place was without enemies and completion trigger.
Now there are enemies, but something is still off. Removed the quest giver for this reset and will hopefully be fixed for the next one. Keep up with the bug reports!
