I have problems whit spawning certain vehicles from other makers of custom scars all of them have one common and thats a weapon mounted on them, what hapens is that they wont spawn and error apears whit report in the console so I tried to post the original scar tank and I end up whit the same problem I looked it up and I got this all the time, when its custom scar the conflict is between scars slim and the custom scars, can it be related?
