EUP manager didn't detect my Law and order uniforms at first, needed to reinstall it manually, didn't have to reinstall other skins though, eg; LSPD Uniform pack Cranston RI by GrandTheftPD or St. Martin Parish Sheriff's Office EUP uniform by vulture001...
I did change around 20ish default cars for real ones all day to day... sadly i replaced all of them (mods/......./vehicles.rpf) and not making them as an add on via modding folder (mods/..../MODDING/..../vehicles.rpf... The irony of it, steam™ decided to update my game after I finished replacing them, and when i reverted... they didn't...
Learned my lesson...
