When I try to open an old game started before I got 1.22, it won't work. People have talked about patching in the middle of the game, but that doesn't work for me. When I try to load it, an error message comes up that says something like "Error: DATE" and when I close it it pops up again, and does that 4 times. Then it says "error reading file" in the baige civ color.
