yep. seriously though, if only 56 in stock you can only buy 56, that's fine. But we will let the buy option move to 57? And when it does it will simply allow the buy button to click with no effect? And while this is happening we will hide the total available from you meaning you have to cancel and spend another 26 seconds waiting for it to get to 56?
If I was being cynical I would say lets just consider trade dead in the game known for being a space trading game. But hopefully these will get sorted soon.
