I apologize for the MP dumps. I've addressed this multiple times in other threads but they've been buried so it isn't because we are ignoring it or trying to hide it - its just impossible to comment on it everytime it reappears in a new thread. Tech support has also been in email contact with a variety of people (including some in this thread).
The MP bug is 1 of 2 major bugs we are aware of and its a sync bug. Statistically, it is very rare which is why it is so difficult for us to track down (we have yet to see it ourselves but we have something going out soon that will help us find it from those who do get it). Also, any multiplayer fixes are scheduled to go out in 1.1 not 1.04. They are in seperate code paths and completely seperate systems being worked on by completely seperate people. This isn't a matter of just throwing the fix into 1.04 and 1.04 development is not slowing down 1.1's development so don't feel we are wasting time on 1.04 (balance + misc) when the *real* bug is in 1.1 (multiplayer).
Now, to save you all a lot of headaches - the nature of the sync bug is that once you've had a game where it happens it is very unlikely you can recover from a MP save game. If you load the MP save game and continue to play you will crash again. You will then load a more recent save game and crash again. The crashes will come more and more frequently. If you see this behavior just start over as its very probably that its the sync bug and the crash is nothing to do with your machines, network, or drivers.
As soon as 1.04 is out I am going to make a post looking for volunteers. I have a special 1.04 build that will track the synchronization info we need to track it down. Since we can't recreate it we need to have a few players who it happens to regularly to play 1.04 with this build and then send us their logs when it goes out of sync.
Finally, I'll make a sticky in the technical thread covering most of this info so hopefully new people with the same problem will be informed on what is being done and what the source of the problem is.
P.S Minidump is the generic term for a general crash - it could be anything and is not caused by any specific problem. We can decode the minidump to get useful information on the true nature of the crash.
