Some GT3 cars in rFactor 2 not working, please help??

[masaki7026]

Upon loading the game up, all but one of the cars in the GT3 Challengers Pack and one of the cars in the GT3 pack fail to load for some reason, citing "requires unknown base mod to be installed". I've already verified my game files on Steam and yet they won't work. Can anyone help?

Hi, had the same issue, go to the Steam Workshop, uninstall the VLN-Pack, then install it again and start the game. Maybe you have to Restart the game once before you install the pack again.
Hope it works.
Stay health, greetings from Switzerland.
