I have a game (save included) where I'm about to get the eureka moment for Machinery by upgrading a Slinger to an Archer. But if I do that, I end up with a negative amount of gold and obviously problems ensue. I tried various thing with the save, and noticed that if I get rid of the Professional Army civic the mysterious gold drain gets even bigger. This supports my initial hypothesis that there's a following kind of bug in the game:
The game subtracts your gold after a unit is upgraded. During the upgrade, If a eureka moment completes a tech that unlocks the next unit in that line, the game gets confused and makes you pay for an upgrade to the newest unit, even though that's not what you upgraded to.
But that's just my best guess. Am I actually on to something, or is there a benign reason for what happens in my game? Please do try the included save. I'm playing on Linux if that matters.
