Due to some unfortunate bugs in the 1.3 patch it will NOT be used for matches. this is effective immediately. all we can do now is wait for the next patch (1.31 anyone?).

Soooo... hold off on applying that patch if you haven't done so already. And if you have patched you should do whatever you need to do to back it off.
