This only happened twice, but it's definately worth mentioning. When loading a multiplayer game, we have seen the status bar get up to 100%, then the compressing file message appears again, and the game reloads. It just keeps transfering the save game file until we back out and restart Europa. We got around it by simply placing the save file on my ftp site and transfering it that way, but it's still a strange and annoying bug.
