Done. Interestingly, mafia doesn't seem to be aware that drinking it fails - it successfully removes it from inventory and everything. Not like it's a huge issue, and if I remember to verify if that's how other drinks work or if it's a part of special steel margarita code, I should write up a bug post on it.
Anyways, BCA should skip getting SM on future GN runs. Yay. Meh.
