Invalid hash error when trying to spawn vehicles from my custom dlcpack

So I have a custom dlcpack, it is added to dlclist and extratitleupdatedata. It contains the vehicle files themselves, carvariations, and vehicles.meta. The vehicles.meta file lists the model name and txd for each of the vehicles, aswell as points to a vehicle model for the handling. When I try to use the rage console to type "spawn MODELNAME" for any of my vehicles, I get the invalid model for hash ###### error. I'm not sure what's going on as I haven't changed anything other than updating gta, lspdfr, and ragepluginhook to the latest versions. What should I be looking into to find the problem?

Any and all help is much appreciated 🙂
