There's quite a lot of stuff on here that is outdated now, some of it works and some of it doesn't. I had to find out the hard way. I could just hook you up with all of my files if you want? There are a few projects that are still ongoing in there, but the schedule and gameplay aspects are absolutely fine so long as you plan to play a UK Flat only save (I'll send you the files again once Ive finished modding other modes). This would just be a nice easy switch files job for you. Let me know if you want them and I'll get it all on media fire tonight.
