Lost entire army and most of my peasants...

[DGraviton]

As title states, lost my entire army and most all of my peasants when someone tried attacking my homeland. The prep phase went by as normal and as the enemy entered the map I received the "Out of Sync" warning.

After this it reloaded my homeland and lo and behold it was all gone. No battle took place, none of the buildings seemed to have been damaged at all. Any help would be appreciated.
