Hi,
The shortcut was removed but your configuration still contains it for some reason - the migration must have failed to remove it for you for some reason when we made those alterations.
The reason you see no movement using your spooky ghost shortcut after running outline is that outline sends a G91 Z-5 movement at the end to go back to the original position - so all movement is incremental. The ghost shortcut just sends “G0 X0Y0Z0” - and an incremental movement of all 0 is not a movement at all.
If you want your go to all zero button to always work in all scenarios, you can make a custom macro that is just “G90 G0X0Y0Z0” and keybind it to the same button your ghost shortcut is on your keypad. I’m also going to make some alterations to the outline tool to return to the original movement modal after outline is complete if it wasn’t G91.
Past that, this isn’t going to be an issue for any other users since they (likely) won’t have the ghost shortcut kicking around.
