I tried for months to find how the barter system works with the current sign shop plugin. Apparently, there is a “barter” feature, which uses [trade] signs to allow a customer to trade items for items, instead of trading items for money or money for items. I fear that this feature of the plugin isn’t working, because I tried in countless ways to use it, but every time the game log said “This shop is overstocked”.

Now, I know that the [trade] feature isn’t used by many people (Apparently noone, because these problems were not matter of discussion before), but I am strongly convinced that by fixing that feature (or “adding” it, if the current one isn’t useable at all) it would allow to start very interesting economy systems within every crew, adding for example custom crew currencies etc.
I am open to explain how I encounter that error, and to elucidate all i can about the matter.
