For those of you having issues Blinking on Archwings:
This seems to be affecting players who have never customized or manually defaulted their controls (this would include brand new players or players who have never ventured into the Customize Controller screen).
But fear not! We have a workaround for this: All you need to do is go into your "Customize Controller" screen in your Options and "save" on the way out - you do not need to make any changes to your bindings! Simply save and exit.
