Summary: Command & Conquer Generals network fails mid-game (mismatch in synchronization data) Product: Wine Version: 1.1.25 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: kakuremura@gmail.com
Using the workaround mentioned in bug 17737, multiplayer still fails. You can connect, you can start the game and you can play for a while, but after the first contact with the enemy (after a few kills) a message pops up "mismatch in synchronization data".
