In situations where rooms are converted multiple times, the previous room hint ID can reference a room number that is out of range of the new number of rooms. This fixes the bug by checking the room hint ID is within range.
Fix `-Wunused-but-set-variable`, `-Wunqualified-std-cast-call`, and `-Wliteral-range` warnings. (cherry picked from commit d8935b27a9)
