I am also having this same issue. I had no problems until after the game updated. The file I was playing beforehand went to turn 182 before this bug appeared. Started over fresh and I'm on turn 80 and getting the very same issue. On the 182 file I had many planets doing an infinite process. Had one of my planets on the 80 turn game doing the same, turned that off, issue remains. I only have 6 systems on the restart session vs the 18+ on the longer 182 game. Both games playing as Riftborn. Only half the research done on the 80 turn game so the only thing that I do know is the issue appeared after the recent update.

Any progress on this one?

Seems to be a common problem now, at least there's a lot of grumbling on Steam about it.

You might want to add your report to one of the threads in the Bug Reports forum. This seems to indeed be a common issue at present and it's useful to group them together if possible.
