The biped I am using works fine normally, however, once I set it's stance/seat to alert, I can no longer move sideways or backwards. The animations for both are identical right now and the animation still plays, I just don't go anywhere.

I have looked everywhere I could think of for a value that might be set wrong, but I could not find anything. Does anyone know if there is a fix to this, or at least why it's happening?
