So I was watching a recorded game and everything seemed to be going as I remembered, but half way through, it started doing things that never happened in the game. All of a sudden, ships seemed to move at random, nobody spent any resources anymore (they all just accumulated them). It was totally weird. Has this happened to anybody else?

Btw. this was an automatic recording (as I can't figure out how to save a "normal" recording). Is there a way to resave a automatically recorded game as a normal one?
