Me and 2 of my friends are trying to play multiplayer skirmishes with each other, but all of us eventually get a crash somewhere between 15min to 30min of playtime.
We reinstalled several times, we've installed it the same way.. We use Hamachi to play with each other online. We usually play 5 or 6 player maps, 3 players vs 2 bots or 3 players vs 3 bots.
Here's the error. We all get game.dat errors. Not at the same time, but one of us always does.
