With the official version of the 1.2 patch, I have encountered a nasty bug. I actually described it in a post here before as a random crash bug, but now I have seen it is not random. The bug appears when a computer planet is ready to defect to me. Sometimes I will be shown ships moving on and off that planet on the control panel screen during the start of my turn, when there is also a pop-up window telling me something. If I don't shut the window while the ships are moving, the game can crash to the desktop. The exception is during research, when if this bug happens, it will always crash.
If you check my list of submitted games, you will find that most of them are Cultural Conquests. That's always how I intend to play the game, so this is a major bug for me. I would appreciate any advice on how to get rid of it, or at least deal with it better.
