indeed i found the problem, a lamborghini had vehicle mods for m4 and z4 )) thanks

So I chose several add on cars carefully, I installed them correctly, all work but in the menu of add on car spawner mod there are two models of cars I do not have in my mods folder (dlcpacks) at all. I checked all the cars dlc's with openIV and those models do not exist. The models are M4 and Z4 (I thought they were also added to one of the dlc but no ) . They only apear in add on car spawner mod menu and it is annoying as hell ) does anyone know any solution? oh and when I try to spawn them it says can't load model..
thank you for your help
