Hendrik Leppkes:
    - Fix restoring the current map location while in micro dungeons
    - Make the timed update upgrade safe and avoid having multiple active timers
    - Run a timer to catch floor changes in multi-level micro dungeons
    Multi-level micro dungeons do not reliably fire any events when traveling
    between different floors, so instead run a one second timer to keep
    updating the map location while inside a micro dungeon to catch those
    changes.
