Game! - Where the stick is mightier than the sword!

The software tester in me just had to try this.

If you put something on the swap shop and then remove remove the rm from the a attribute from the remove link you can trade with yourself. And when you confirm the trade you get the Whoops! screen.

The funny part is I actually handle that case already (with the message, "Trading with yourself?"), the problem is that i unset a variable when doing so, but then try and use it later without checking if it's set in that certain case.

Anyways, fixed.
