I can confirm this a is a Major bug. Happens in both Singe-player and Multi-player. More severe as the save file/database gets bigger. Starts at about 5 gigs save file size and snowballs from there. Particularly major impact in large space battles where the writes to the database can completely be overloaded to the point where they simply will not write to database. Then you have to leave the playfield and reload it for them to catch up.
