For me...

I'm playing on the 2nd largest map and the game freezes regularly and has to be killed in task manager.  I consider it a miracle if I can play 4 turns before it freezes.  Game performs well when it's running but the slightest thing like zooming out can cause a freeze.  Now my game seems to want to insta CTD while going thru the colonize planet dialogs - happened 2x on the same planet.  I have a beefy and up-to-date PC and no problems with any of my scores of other games currently installed.  This is getting to the unplayable stage for me since I'm sick of replaying lost turns.  I wish I could crank autosave up to save multiple times per turn.

Side Annoyance - it's annoying when the build list for planets switches to soil enhancement (or the like) mode and you can't place anything else without getting out of that mode.  On a new world that's not something I'm going to build early but it's constantly "getting in my way" of doing what I do want to do.  I think it would be preferable that this type of improvement NEVER auto engage and only be manually doable.

PS - My login doesn't work at your support site even though I can login just fine here.  Tried to register and it says I already exist.  Seems like with this new fangled internet that the uploading of the multiple files you want for bug reporting should be automated anyways.
