Whenever I host a game, "connection to server lost. Return to main menu." at some point in the game. Whenever I join a game, "failed to join game. Returning to main menu." I even just lost connection while in the lobby of a game I managed to get into. This happened very rarely a few months ago (I haven't played in a very long time.) How can I fix this? Also, I use hotbuild mod, but I don't think its the cause.
Same thing has always happened to me. I thought the game was just buggy (gamma and all), but you'd think more people would be complaining about this if it happens to everyone.
