Currently, the crates you get from missions are unsellable if you put it into a vehicle and press sell cargo it counts as nothing. You have to manually take out the items and put the items into the inventory of the vehicle. Which is time-consuming and not worth it. Also, I don't know if this supposed to happen but you don't get any pop tabs from the crates either. Which could be intentional but I'm not sure. Then there's the towing which doesn't work but I've seen you guys talk about that so you already know about it.
