I've just started playing civ 5 again, so tried to submit a few games. One of which was a huge marathon game. After it finished submitting, the message said 'thanks for submitting blahblah', where blahblah was the final save name. However on the submissions list, it's showing as a turn 0 game. Had a look at my list of saves, and the later saves are all 2-3 MB, which I assume is why they're not registering. Any way to make them smaller while still being in a format the hof submitter will accept?
