Now I'm too scared to add another mod. I'm afraid that if I add another mod I'll corrupt everything and I'll have to start over again from scratch. It's like I've constructed a gigantic house of cards and now I'm afraid to add another card because the whole thing might topple down and then I'd have to start over again.
It occurred to me that I could just back up my install directory. It's not like I don't have the hard drive space. But surely there's a better way to do this?
Has anybody tried something creative, like a version system (SVN or Subversion or something)?
