I have tried it a couple of different ways, with several time increments. I can go lower than 25 seconds, but not above it. I literally let the program run in auto turns for a couple of hours while I fixed dinner, and then another couple of hours afterward while I did other things on the computer.
No luck.
At this point, I am starting up another game and hoping I dont hit this again. I know Steve has been able to fix these in the past by fiddling with the database of the affected game, but thats a lot to ask of him. At this point I was sixteen years into the game, so its not the end of the world, just frustrating.
