You rock Merkur!

Good job Merkur, you're a excellent coder =).

[Drawde]

Great job on fixing the merchant code!
Now I can finally use 2.4 (with the next beta at least) :)

Have you also fixed the bug with purchasing stackable items? (they default to 0 items in the stack no matter how many you choose)

umm i just changed some minor things in this part, its not that big heh.
