While I was looking at a different saved game scenario, I noticed that the workers were able to build airfields,outposts & radar stations from the start! Since this was for sure a bad thing, I went and tried to 'correct' this. Long story short, I have now had to reinstall all of Civ3, PTW, and Conquests. Yes, I botched things up THAT badly.

Needless to say, I lost all my save games, too. I should have copied them somewhere else, but by the time I got to that point, I was just not thinking clearly. Though with my files being corrupted/misplaced so badly I doubt they would have worked after the re-install. The damned thing still isn't right, I loaded a Conquests Civ-content scenario, the Teturkhan one with cities, and the start paragraph is all whacked out and talking about Prince Henry the Navigator and his school being around in 4000 BC....
I'm going to have to download the big file just to play this scenario, though I do have the 2.1 part of it at least. Small comfort. Does anyone else get these kind of problems? I know it's because I play a lot of modded scenarios, but I don't know how to protect the original files when I go to play the scenarios. If anyone could point me to a primer on the file-switching and how to do it properly, I would appreciate it. I'm sure someone has posted that on this website before.
What freaks me out is that if I try to start a new randomly generated game, everything seems to work properly, it is just when I go to scenarios, especially the ones with a loaded save game, that get all goofy.
Hopefully I will be able to get it back together soon. I am a bit ticked that I could not finish that Italy game, I was pretty sure it was going to be a sure win fairly soon, but there was just enough doubt that I'm going to always wonder about it.
Edit: Rocoteh, I just DLed that 134 MB file again, but the note you put there has me a bit confused...Since I did a complete reinstall I should use the 134 MB and then the 2.1 file right? I don't see how that note to not use the 134 MB with 2.1 would apply to my situation, but I want to be sure.
