I observed this bug on the latest available build, r10968.
I tried to /chug 3 around the worlds from the chat command, which failed because I only had 2 in my inventory. I /chug'd the 2 I had, and when I looked at the "Session Results" pane in Mafia, it showed "around the world (-5)". I'm not sure if this is more general than the case of "fewer items available than attempted to use", but it was strange enough I felt it was worth mentioning.
