Search doesn't seem to be working and not sure if this goes under DA or Bugs...so:
Have no idea what the trigger was and figured it would go away, but my populations are locked. I think it might have happened when I put my economy into the red with a quick-buy but that's a pure guess. One population is stuck at 2.52/18 100% approval the other 18/18 70% approval and not sure how to troubleshoot the problem.
