attempt to recover from failure to write to map
There have been reports of large, distant-from-player Digtrons apparently failing to completely write their layouts to the map, resulting in an inconsistency.
This adds an attempt to brute-force a solution. When a map write fails it will be retried until it succeeds, or until 1 second elapses (at which point the write is aborted in a hopefully somewhat clean manner).
