When I select a mining tower, and try to assign a truck from the default zone by alt-clicking the plus, the game opens a pop up asking if I want to add a new truck from the vehicle depot. I cannot add any vehicle like this. Someone on reddit said this is caused by this mod, but I myself don't know. This is quite irritating because it gets in the way of a big QoL feature. You can find the save file on google drive here.
