Ok. So I've been fiddling around with ToT some seeing as this is beta and I wouldn't be a good tester if I didn't try to at least break one thing.

Something I've noticed is that, when you have an item pending in trade, it shows in the list when you want to give a personal item. Now you can give that item to the trick or treater then accept it from trade to get a an Item showing x0. It gets stuck in your inventory and there's no way to remove it from what I've noticed.

I'm currently on my kindle so I don't know how I might offer a screen shot of the item currently in my inventory.
