Characters won't move

Do you have another controller to test with? Something being new doesn't mean there won't be a problem, and sometimes items get shipped without catching issues. I also wonder, does this happen if you try it in the firing range or only in a match?

If the issue persists with a different controller, it might be a strange connection issue. If you record your gameplay a clip of this happening might help as it would have the relevant network status indicators, if that's a factor. 

Thanks.
