That's just where I put his mods.
It's ok too. I did used to update to the latest using the handy Better Repack exes. However, I had a ton of issues with my game after going from R12 to R13. After talking with a mod expert called ManlyMarco, he told me I could manually update all my mods folder on a "dummy" build of the game, then pull everything I want from the latest R13, R14, and R15 repacks manually to my R12 copy--which still works flawlessly to essentially have my cake and eat it too. I have yet to learn why the R12 works better. But it does so...
