I'm new to modding in RF2 so please be patient with me. I wanted to make some cars faster than others like in Formula 1 where each rcd AI has different physics,when i save the edited hdv file the mod disappears from my game and i can't see the cars anymore. I guess i'm saving the mod the wrong way in the mas editor. I was just dragging and dropping the renamed edited hdv file and saving inside the mas. Is there a proper way to do it or am i missing something?
