Corrupted info files can cause the configs to disappear for some people, it was the case for the CrashHard Classic mod and still is for the FR-17 mod, you should take a look at those.
I think my own real big complaints about it so far are the lack of a roll cage option, the rear indicator flares from the Moonhawk still existing, and the tail lights not lighting up when you flick the headlights on. Other than that, this is sick!
I gave the 2 configs ( Bullitt and Detective ) there own Info.json to see if it fixes anything, the drag and stock had shown up so that's what I was thinking it was.
I will certainly be using this mod quite a bit, as far as bugs go there is nothing that hasn't been already said. Nevertheless its really good tbh.
I was having the same issue, but when I opened the .pc files for the missing configs with notepad++, the configs popped up for me.
Cool! I also noticed that the hood, front and rear fascia, and the front and rear fenders are see-through from the inside but are solid from the outside.
Already fixed, Just have not uploaded as I am fixing other stuff like innerfenders, I also already have fixed the engine not turning on after turning it off.
