Hmmm...

I don't know if that's what you were describing as trying to do, but you might want to go to Settings in the UPlay launcher and uncheck save game synching as well as checking off "play offline."

At least that way you can see if it really are the save attempts to the server crashing you. I don't think it is, but it's worth a try. Also, even though you switch off "save to server", your savegames will STILL be saved to your harddrive, so it's not like you can't save anymore.
