Hello, I've had this error several times and I think it might be a bug.
I have a folder on one artboard called 'want' and I copy paste the entire folder to the previous artboard.
Then I control-C create a motion transition from artboard 1 to artboard 2, and it does not recognize the folders as the same component.
Then I go into the motion editor for that transition and I see that there are 2 instances of 'want', so I selected them both and click 'link layers' in the top right. And this does nothing.
The whole artboard goes blank (pops to white) then the next artboard pops on)
NOTE: Within the folders, there are subfolders with generic names, like 'group' but changing these doesn't seem to solve it either.
Am I doing something wrong or is this a bug?
