Ok, SO, this is what happened. I was playing a random medium map as my beloved Advent Loyalist faction, when I ended up having to go. I went to save the game and noticed I could 'Cloud' save it, or what have you. I did so just to see how it worked, and well later that day I came back to play and I tried loading said game. I got a mini dump, so I just decided to make a new game. I was very unhappy to discover that I could no longer choose the Advent to play. I uninstalled and reinstalled it and still nothing.

Any ideas?
