in comparison to earlier 6.x opt-ins i don't get any semi predictable crashes from invasions, but it the seems to crash much more often. it almost always happen when i have something idle (planet/ship etc.) and click at the idle x button in the lower right of the main screen.
i never had these problems with the 6.2 opt-in, this was very recently with the 6.2 release version. the 6.2 opt-in was very stable for me. i also made sure to start a new game.
anyone made similar observations?
edit: fixed, see reply 5
