[Feedback] Occupation victory

When playing with the Occupation victory win condition enabled, once the planet is captured the timer starts. After around 7 minutes however, the timer disappears. After waiting for roughly 8 more minutes, it gives me a mini-dump and kicks me out of the game. The mini-dump seems to coincide with the 15 minute win timer expiring. It's happened in the same way in two games both using the occupation victory win condition.
