Hi Tucker D Dawg,
Thanks for reporting this issue - I wonder if you could please reply with a screenshot of your controller layout (Options -> Customize Controller). It sounds like you previously had "Move Up" bound to LB? if so, I assume you had "Move Down" elsewhere? Part of our last update was designed to replace the "Move Down" action with "Move Down / Dodge / Blink", so I'm curious if this worked for you but is on a different button somewhere.
Any extra info you can provide would be super helpful, thank you!
