Whenever a fight happens while trick-or-treating (as well as the first action you do after scoping out a new block, even if it's getting candy), mafia counts that fight/action as happening in your previous location, incrementing the turns_spent of that location, and doing any other related handling related to that location (such as increasing manorDrawerCount if you were previously in the haunted kitchen) instead of doing it in the Trick-or-Treating location.
