Found a bug.
My latest character was cheap and only gave his runners the moderate protection, not the full set. So when I started to play the FoV part of the game, I had to re-buy the basic protection before I could buy the Advancd, 4000 gold gear. That added 6000 gold (which I had already paid earlier) to the cost of the gear.
Also, the second door upstairs in the Prancing Seahorse, the one opposite Thomas's room had the right text, but the same voice-over as Thomas's door.
