OK - game is back up with 21+ hours in the turn. It shows Rhoth and Ephack as having played.
Of the recovery saves - Rhoth's was time dated at 12.07 am. Ephack at 12.10 am, and snoop's at 2:35 am. I reloaded the snoopy recovery save, which probably means that is about when my computer crashed. I think. Rhoth and Ephack may want to check their turns to make sure what they wanted to happen in fact did.
Checking civ stats now.
