Oh damn, do you happen to have any screenshots (e.g. mod folder, in-game stuff) since I can't exactly figure out why this is happening
Yes, for sure, I appreciate your help! Heres a screenshot of my save location, and of my repository in-game .
For me, it's probably some sketchy site, it looks old and you won't really find it anywhere else, and probably without a translation
It seems like you're using the old and obsolete mods folder. You gotta locate to Appdata/local/BeamNG.drive/0.26 instead and create a mods folder if there isn't any. If there is, put the bmw there and all zip mods go there instead
