I’ve been playing a bit with keyboard bindings and noticed that if I leave a binding blank it will trigger on another action. In this case, when I pressed the button to walk to mouse, my character would parry first and then move.
I will try to see if I can reproduce this and update accordingly.
EDIT 1: I can confirm it also happens to other actions like attack. I can trigger a fully charged attack and then my character starts moving. it probably also works with other actions.
