You don't happen to be using Robo-Miners, do you? For some reason building one of those (or, presumably, the AI building one) crashes the game at the moment.

Only once have I ever made large scale use of robo-mining (in a Star Trek game where the Tholians had massive, and I mean massive, advantages in radioactive mining). It simply isn't a path I bother to go down. I guess perhaps the AI is doing it though, who knows.
