Preventing Cargo from draining the Rockbox

[Brixx79]

I much prefer the rockbox method of 'dump and forget' than having to micromanage quantities I'd want to sell at what prices. That's what cargo does. And I usually just have cargo come and ask/steal ore on maps like Donut3 where we're close instead of buying it.

You could always build vending machines with the ore if you really want to control distribution somewhat.
