Mafia doesn't "count" things as costing adventures unless KoL itself tells you after the fact that your adventures remaining have gone down.
I assume that what you meant to say is that we printed your adventure count in the gCLI or session log when you visit the cellar.php map, rather than only when you visit a square. If so, yes, that is not intended. It's also completely not a big deal for you to simply ignore the adventure number on that line and just smile happily when you see the same adventure number in the log when you actually go to a square.
