Controller is not mapped correctly.
Not sure if this necessarily counts as a bug but for some reason, when playing with controller, the Attack button, RT, is switched with LT, for block. The indicator for this is still RT for Attack, and LT for Block though... I was using a different controller configuration through the Steam Overlay, and it was working yesterday. But today, my controller wasn't recognized when I booted up the game.
Unplugged it, plugged it back in, and it went back to the default controller setup, not really a big deal if it weren't for the fact that the controls were in the wrong place, and no way to edit the mapping.
