Vehicle Salvage
What am I doing wrong?
So I subscribed, downloaded and enable the mod. It is the only mod I have. Single player. Standard map. It worked once the day I installed it and then I didn't have a chance to try to use it again for a few days until I got back to my base. I have a full torch and mask in my backpack (and tried main inventory also) . I tried on wrecks and functional vehicles. I don't see Salvage Vehicle shown in the list. Am I missing something simple??
