Is the Ankh-Morpork Asylum mission bugged? I keep trying to find it, but I can't seem to find it anywhere. It seems to point me toward the graveyard, but upon entering there, the mission disappears in my log, and no location seems to appear. Before trying to go there, I hacked their system as advised, then got the explosives, then hired my team (Ricky, Verum Julos, and Argyle). I can't access it through cabs or Mars, either, if that's the intended path. I'm at wits' end; did I sequence break somehow?

Edit: I was able to make it stop pointing toward the graveyard by dropping the mission through Frosty (and then picking it back up by talking to Mike Score), but everywhere I go, there's always a "0" in my mission details, above trying to go to the Asylum. It existed *before* I managed to drop the mission, and it came back once I took it back up again. I don't understand that, don't know if that's important, but thought it as worth mentioning.
