Just joined beta. Have played around 15 times. This happened only once.
After about 10 turns, and before I even met any AI players, I got a screen that said "Victory Condition - Conquest", or something like that. I then started a new game, but I got a white screen and it seemed like the game didn't reset - e.g. it showed Spell Points etc. that looks like they were carried over from the game I "won". I closed and restarted and haven't had the issue since.
