Not sure if this is the right place, but eh, here goes: When I spawn certain vehicles from various DLCs (specific ones I've found include the Slamvan Custom and the Elegy Retro Custom) using trainers etc, they have no customisation options. At all.
Let me elaborate: I can drive these vehicles into LS Customs as normal if spawned via trainers or with traffic mods, but when the menu appears, 'wheels' is the only option. I can't change the colour or performance tuning options of these vehicles. Even when using trainers that allow vehicle customisation, only the wheels can be changed. Lowrider customisation options don't even appear in menus, and trying to customise the body colour or anything except the wheels crashes the game. It seems like the game is ignoring the vehicle mods files, or even basic customisations. I've checked some of the relevant .xml, .meta etc files but can't see anything abnormal.
I realise this is a weird problem and suspect a full reinstall is in order, but if anyone could point me in the right direction that'd be awesome
