I keep getting a "Fatal Error" crash playing the Necron campaign.

I have the following missions active:

The Prize - Part I
The Trail
The Fallen Dynasty

I just conquered the Agripinaa primary system, which activated the Fallen Dynasty. Once I ended my turn, everything went fine til it cycled through the Necron turn on Agripinaa sector, then the crash happens.
