We were playing 4-player game and the game stopped working at turn 102. We can all still click buttons and the info screens open up, but nothing changes in the game. The ships won't move, battle won't commence etc.

I tried loading it in single-player and it still won't go past 102. We replayed from turn 100, and again it got stuck at 102. 

I am attaching the game file. Hopefully someone can help with this!
