I played a multi-player game of the RA mod and early in-game after getting War Factory and a few Harvesters up, both games crashed all of a sudden. My terminal showed the following debug:

We two both are located in Netherland.

Another crash when I pressed 'Abort' on the connecting tab after connecting failed and asks if you want to retry connecting:

This is what is known as a `desync'. If the game state on different machines diverges, we crash instead of letting the game continue (which would lead to very odd behavior, as you would be essentially playing different games).

To track down the cause of the desync, we need the sync.log of the two diverging players so we can see what is different.

Were you running the latest build?

Easiest way this crash happens is if you or someone else were running a different version from the others playing.

Yeah we were running different versions, I think it was christf who pointed that out. I can't get both the latest svn build and the released build (from the download page) to write stuff to the sync log, i.e. the file is empty.
