Thanks for trying it out <3
I’ve got a bug patch ready to go for next week. I’ll look into the issue of people outside of vehicles consuming fuel.
Each person / vehicle has a carry limit for consumables. Getting into a car or truck will let you carry more / use more of the pickups. Outside of a car your avatar can only carry 5 of each.
There was a bug in the web version that prevented you from fixing the vehicles without getting into them first. You should have all the resources you need at your starting outpost to fix up the closest car.
Edit: Found the bug causing fuel consumption it will be addressed in the new patch
