Well I got to experience the late game ctd. Found out that 1 of my planets was update to a Citadel of Repression and showed 0 turns to complete.So every time I was able to load the game (sometimes it wouldn't) and clicked next, it went away.I did notice just before the crash that the idle colony button lit up in lower right corner just before the crash. After canceling this out I was able to continue on with the game. May not help everyone, but it's something you may look for if your's crashes.

Ticket submitted with info.
