So... for example, my current ship can hold 100/100 Medicine.
So I dock, and buy say 200 medicine.
But when I use up the current 100/100 medicine, where's my spare 100?
This also happens - I had 160 Medicine, so I docked and bought 500. When the 160 was used, I can't find the 500 I bought anywhere?
I was thinking "Maybe it only lets me buy my max, when it does the sale."
So I tested it - and it seems to indicate I am buying the excess - but then it's just gone?
