i cant get any of the custom vehicles to spawn, it seems to let you buy them (might not be taking the scrap) and then doesnt do anything when you try to spawn them. any idea whats going on?

this is the response i get in console on any of the custom vehicles
Couldn't find prefab "assets/custom/atv.prefab"

Do you own the custom vehicles? to use those you need a 3rd party plugin from Karuza
