Market Window shows recipe name as Kismet +6 0x0.000030P -1022acc
It does the same thing if you have the recipe on hand, and drag it to the chat window. As a matter of fact, any recipe that has a % in the name will do this.
I'd say it's a bug caused by the % being interperated as code, instead of plaintext.

Biggest Troll on the forums? I'll give you a hint:

I know exactly what's happening there: the enhancement name is being sent directly to the text-formatting function, when it should be sent as a string parameter. It's a common newbie programmer mistake.
(Specifically, it's being interpreted as the "%A" format specifier, and the next (probably non-existant) element on the stack is being interpreted as a double-precision floating point number.)
That can't be right.
Doesn't seem to appear in the description or when in inventory; just in the market window. Persists if I remove it from market and re-add it.
