I made a screen recording here https://app.screencast.com/Cabu3HYJ8a7Iq?conversation=D0omeOxtNugiIeVWErAH71
Basically the move gizmo no longer shows when I select control points. I feel like I've probably enabled or disabled something in inadvertently. I've tried changing the control point type to no avail
And immediately I solved it. It is due to having 'individual origins' set as the transform point instead of 'median point'. Individual origins is activated to scale down the ring loop on the thick cable so if you're having this problem just switch back to median point
