Old quests/buildings locked despite level?
So I took a lengthy break from the game last year, in which time several new buildings and characters were released, and all but the premium ones have been locked since I returned to the game. I've been busy with the monorail and various events, so I hadn't bothered to really check them out until today. A couple I'm especially interested in are the Slaughterhouse and Dr. Monroe Therapy. I finally looked them up just now and it seems like all you need to unlock them is to be a certain level (52 and 51, respectively). I'm at 102 For the Slaughterhouse it says you need to start the quest to unlock, but when I look up the building in the wiki, it says to start the quest you just complete the building I feel like I'm missing something really obvious...
