Cargo shuttle does not take privately bought cargo items with it.

[MisterGrimm]

When you buy items from the cargo console anything labelled as privately bought will not be properly moved to the cargo shuttle.

Reproduction:

1. Privately buy a item on cargo shuttle
2. Move it to checkout
3. Send shuttle to station
4. Shuttle will have non-private items bought, will not have privately bought items.
5. Cargo console says privately owned item is still in checkout.
