What about Barges?

[Lord Chaos]

The following code checks if the barge is carrying a mineable item.
If it is carrying a mineable item, it will not be allowed to make dock at a profitable destination.
If it is not carrying a mineable item, it is allowed to dock.

```
if (barge.carryingMineableItem()) {
doNotMakeDock();
} else {
makeDock();
}
```

This code assumes that there is a method named `carryingMineableItem()` that returns true if the barge is carrying a mineable item and false otherwise.
The `doNotMakeDock()` and `makeDock()` methods are used to indicate whether the barge should or should not make dock.

I know Freelancer has diferent coding but the principle should be the same
Just a thought

It seems that the implementation of separate buy/sell screens for POB's will settle this issue for those bases at least?

Hum... what about this idea, no coding needed:

NEW RULE
Barges cant carry transformed goods. if we catch you breaking the rules you lose your Barge
You can buy another one as soon as you whant, dont forget to break rules again so the Team take another Barge from you

Edit: As far as i understand the sell/buy pricing problem isnt solved, the processing of mineables into a new item does it naturally, so although some may think it would need to re-write the entire PoB code that isnt true as it can be solved with a single line of code.
