Came across a really weird error. I apologize in advance for the lengthy description. As I was playing I had reason to want to jump back to the beginning of the turn because I had messed up something big, but when I loaded my last save without looking closely, it was two turns ago. No matter, must have just been an oversight on my part. Played through the two turns and went to save to find the original save for that turn missing. Huh, okay, maybe I had actually forgotten to save in the first place and that's why my "latest" save was two turns ago. So I go to save this turn and I get the popup saying it already exists, do I want to overwrite, but that year is definitely not showing up on the list of saves. But what the hell, I say yes, save, reopen the save screen to doublecheck... and it's still gone. Try to save a third time and again the game insists the save is there and I'm overwriting. At this point, I shut the whole game down and check the file folder and sure enough it is there. I reload Civ4 and now the save file is on the list, but when I tell the game to load it I get the attached error message, "Cannot load version 1150352383, expected version 302 or lower". It was a repeatable error as shutting down the whole computer and restarting brought back the same error. I can't attach the save file however, as renaming it somehow completely fixed the problem and I cannot recreate the issue by replaying an earlier save to that point. So just a heads up I guess that something bizarre briefly happened, and renaming a "broken" file is an effective workaround.
