Preventing Cargo from draining the Rockbox

[Decarcassor]

Yeah you can just hold the sales of top priority materials until you get everything you need.

If there is one issue with the rockbox is thats its not access locked. Anyone can just enter the mining department and take stuff from it. And since miners spend a lot of time outside, they often can't really stop it, depending on where the rockbox is located in each station.
