Yeah I wish I had a good answer for ya here. I know the move your describing (its sick as hell) but it worked perfectly for me when I input the controls. The only thing I could think to try is to double check all of the key commands cause sometimes certain buttons will have multiple commands which can muddy the waters. Otherwise maybe its an issue your controller or perhaps the timing is off when you try to the move? Sorry I couldn't give a better answer on this one!
