Undetected sync error, have paired save files
LAN game
I played a LAN game of entrenchment and we ended up in two different game states - a sync error that is not detected by the game. I've uploaded the save files here. In my (-jj) save file, light blue's fleet is being attacked by capital ships (screenshot). In the other (-si) save file, light blue's carriers are safe and the fighters are cleaning out dark blue's infrastructure (screenshot). There may be other differences but this is what we noticed first.
Interestingly enough, these save game files can be loaded and both states seem to be preserved: the respective parties will see their unique state of the star system.
As for a possible cause, the only thing that comes to mind is that light blue did alt-tab occasionally.
