Cannot resume 48-bit family blocks search after loading session

[SPINZ1]

Each time a session is loaded, or Cubiomes is launched for the first time after booting, attempting to resume a 48-bit family blocks search from the saved progress results in the search immediately ending with a seed of -1, and the search progress must be restarted by clearing results.

Fixed in version 4.0. - Not fully resolved yet.

When the progress stopped on a negative seed it wouldn't load properly. This should be resolved now.
