Any chance of any game developer input on this thread please? I'm experiencing similar Alien Turn lock-up issues. Playing into a few turns, the alien turns takes forever. When I mean forever, I mean I leave the computer on for a few hours and come back to it and nothing has happened. It's still on the aliens turn. I'm running community edition 0.35. as for the version, I couldn't tell you. I've only been playing it a month or so so I'm guessing it's the latest version.
