Hello there, I have a bug to report.
Two of my nations, this one and Kemet Reborn are thematically nations with large undead populations, so I am delighted to embrace the zombie hordes on Z-day.
While this has largely worked according to plan, and while I've had the two send hordes into one another to drop the survivor numbers low (while leaving about 13 million each time, just to represent the living populations on both nations / to leave something for the undead to snack on), I've noticed that at the 30 minute refresher mark that the 13 million survivors in both nations resets to 18 million survivors.
I am in a password-locked region with just my puppets, where all the other nations were set to kill not cure, so there is no possibility that I am being hit with cure missiles. There just seems to be a glitch where about 5 million zombies cure themselves about every 30 minutes or so.
