3D Sketches in Assembly are displaying as rolled back in Pathfinder and cannot be rolled forward.
Solution
To repair you have to edit the definition of the questionable 3D sketch, save the file while you are still in the 3D Sketch environment, then close the 3D Sketch environment and close/reopen the file. Afterwards the issue should be gone.
