Miscellaneous: Client crash when interacting with banker and merchants

[Crom]

If you have the banker window upen and click on a stack of something and then with the Quantity window open, close the bank window and try to interact with a merchant and the open quantity box, client crashes.

so to reproduce this:

1: go to a bank where you have a merchant nearby, like Rivervale bank
2: open the bank
3: click on a stack of something in your inventory, so you get the quantity box up.
4: close the banker and open a merchant (with the quantity window still open)
5: press accept on the quantity box so you get the full stack
6: client crashes, tested it now 5 times, crash every time.


Might not be the biggest problem in the world but would be nice to remove one more bug that can cause a client to crash.
