My wife and I play Civ4 Bts over a LAN and up until the 3.1.3 patch almost never got "Out of Synch" errors. Now we 3 or more in 45 minutes. We've rebooted both machines, switched the machine hosting the game and started fresh games. None of those attempts have made a difference. We both have XP SP2 with a gig or more of RAM and the network is 100 base T ethernet via a Linksys router. Anyone else experiencing this problem?
