Addittionally, they appear to be the only faction where the two resource buildings have a different output.  A single orchard produces 20 resources every 6 seconds, while the forge (like all other factions) produces 25 every 6 seconds.  This makes the bugged orchard upgrade even less useful.  The forge actually makes more resources per minute.

It looks like you are doing everything right.  I had this game.dat error shortly after I started using the mod.  I only had it the one day, but it happened three times in a row.

The only thing in your post I didn't see that might  contribute to the error is game length.  In my search for answers I read that because BFME was created for the use of single core processors that it becomes overloaded from "high graphic settings" and long skirmish games.  The load builds up over time and the game eventually crashes.  Because all modern computers have at least duo or quad core processors, the individual processors are actually slower and less efficient, but there are more of them, so most programs run more efficiently.

I have tried to limit my skirmish game with friends to less than an hour, and I have turned shadows and shaders off completely.  Since I did that I have not had the crash happen again.

One thing about this problem though is that I don't think there is a precise solution.  I wonder if the modders could change the software to utilize multi core processors?
