I made it to turn 121 in my game

At turn 121 I opened up a starbase build screen and the game crashed to an infinite End Of Turn because it tried to execute AI movement and turns with the starbase screen open. 50% of all game issues are caused by the game attempting to perform AI turns while the player is either in the starbase screen or the shipyard. It seems like a no brainer here but all game activity except for the selected operation should pause when the player opens one of those screens. AI turns and actions should only execute on the game's map screen. Not doing this is just begging for problems with the game. At least this is how the problem appears. When non map screens are opened the game seems to be looking at everything related and there is just too much overhead for the game mechanics to manage. I will note that I am disappointed in the game's AI. Playing godlike with hostile minor civs at the largest map size resulted in 90 turns before the AI managed to break through its hostile minor civs and reach my space bubble. Minor civs should probably be limited to something like 10 ships each. I fought hundreds of space monsters and hostile red ships in my bubble space. They swarm so much even a godlike AI barely manages to break through. It wouldn't be quite so bad if they killed each other instead of cooperating all the time. And why must white ships always be non-hostile to the player?? They become a massive resource drain eventually so I always have to use the console to remove them.
