Please explain your issue is in as much detail as possible.
So I started off playing the main game, was having great fun and took over almost the whole map in my game.
Then I downloaded the Green Planet DLC and started a new game and was loving it until about SOL48, when the game began to stutter, or freeze the screen every 2 to 5 seconds, but only when the play button is turned on, so only when time is flowing does this happen. I can scroll around the map when its in pause mode with no problem, but the stuttering once i hit play makes it unplayable now. I am not using any mods, I only have the main game and the Green Planet DLC.

I tried updating my drivers, clearing all temp files, rebooting, even lowering the graphics quality to bare bones and it had no effect.

The one odd thing is that my saved game from before that does NOT include Green Planet DLC still plays fine at full speed and that saved game had much more progress and stuff moving all over the place than this current stuttering Green Planet DLC save.

Can you replicate the issue?
I haven't tried to sit down and play another game and put in so many hours, no.

If you run a Steam Verify operation against the game, does that find anything to fix?

Hey so what's the verdict on this? Steam Verify shows nothing wrong.
Is the Green Planet DLC just broken and I shouldn't bother playing it?
Is there just some item somewhere causing this that I need to delete?
I'd like to start playing again, at least knowing its not pointless to play when it eventually does this every time.
