Having an issue with adding vehicle mods. I followed the instructions, but there's no vehicle.ide, there is a default.ide but as I saw on another comment that might not be the right place. I'm using a 'free' version of the game and maybe there's some differences in the files? I've tried numerous other mods and none worked, especially the Opel Blitz vehicle. If someone could help me out, give me a thoroughly detailed guide, that would be awesome.
