I am downloaded and installed last version (warzone2100-master-20130921-002120-4f16a61.exe) on 2 PC.
PC are next to each other, connected through a router. When we playing in multiplayer with NullBots, the game is constantly loses synchronization (2+2=5?) about 5-10 minutes after the beginning.
The host PC is running on: Windows 7 x64
The second PC is running on: Windows XP x32
Both PC work great, no system errors and errors with the memory was not. In version warzone2100-3.1.0 no problems. Multiplayer works as it should. We are connected to the network laptop running on Windows 7 x64 and installed warzone2100-master-20130921-002120-4f16a61.exe. I launched the game for 3 people. The second PC got desync after 5-10 min, but the host PC and laptop well kept connection.
How can I find and eliminate the cause?
