Park a transport in Elmenton POB in Pennsylvania and switch to a mining ship. Mine helium. Fly back to Elmenton and drop cargo, then dock. Switch back to transport and tractor the cargo in.
Now, I find that the cargo disappears immediately. There's no one else about, so it's not that anybody else is tractoring it in.
Even after second time you just did not understand that you cant to that? If that would be possible there would be no bussines between other players about prices and thats not kind of a RolePlay thing,you know?
I guess the first times you did that and it worked, a player was close so it didn't disappear. What you need is a couple people that you know mine there and poke them when you arrive.
It was removed rather recently because people would fly into areas cloaked and drop ammo, regens and other stuff. Sometimes even cloak in and tractor cargo. These things happen
