This is probably for @rajaa, attached is a move edge failure. Hopefully the notes in the file are clear, but the overview is window select all the edges in the indicated area, and attempt to move them straight up (or down) in the current CPlane somewhere around 12". Over here the result is fairly obviously unexpected.
Let me know if you need any further help replicating.
Thanks,
Sam
