So I have a rather strange issue occuring and figured maybe someone else has ran into this before. I've been searching for a few days and find issues similar but nothing that has fixed my particular issue.
So I added a few cars from the CHP pack and EMS packs here on LSPDFR. Instead of overwriting, I have been renaming the .yft and .ytd files for each, as well as the ELS xml files. As I have been adding them, I have also been adding the cars to my carvariations.meta and vehicles.meta files that are in my DLC folder. (I have used Albos way to get the pack). Heres the strange part, because I know everyone is immediately thinking its a problem in carv or vehicles files....
The cars spawn.... however, if you go into the rage console and type "spawn" and the list of cars shows up, the game doesn't see them. So for my CHP cars, I have them named CHP1, CHP2, CHP3, CHP3K9, etc.... so if I type "Spawn CHP1", the car spawns and works perfectly fine.
Wasn't sure if anyone had any ideas on this, technically everything is working with the exception of them showing up in trainers/consoles, which is just plain strange to me.
