Hello!
I'm currently nearing 700 turns on my insane game. For some reason the the diplomacy trade screen has been "deteriorating" over time. At first few of the civilizations had empty trade screens as if they did not have any planets, ships, tech etc. Now simply clicking the button that opens the trade screen of a civilization crashes my game every time to the desktop. The empty trade screens and crashes happen only with huge civilizations (power >10 000) so I would suspect that the trade screen simply can't handle thousands of tradable objects (planets, ships...).
Has anyone else experienced this and could there be a workaround?
