The game still occasionally crashes when one team wins while it's showing the moneyball explode. Additionally, after my game crashed with this I got a Data Execution Prevention pop-up. The text in the pop up is: I'm running Windows Vista 64 bit. When trying to add mnc.exe to the Data Execution Protection exclusion list, a prompt informs me that DEP must be enabled for this program to function.
I'm also running vista64 and had the DEP popup on crashes yesterday. I haven't played the game yet since the latest patch (only hosted a server) so I don't know if it's still happening to me or not.
Okay I loaded up the game and jumped on my server and played through a full round of maps. Final map in the rotation was ammo mule, and my game crashed just as we won and the money ball exploded. My server stayed up though and is still running.
