Please do.  I just tried it again on a test.  Select and copy 
components,  paste special/duplicate designators, hit 'X' (and yes top 
warning) and then 'L' to flip layer.

Result:
Bottom layer SO-14 with pin 1 and 14 at the top has pin 1 on the left.  Not 
manufacturable.

Maybe I have missed a step, but I am afraid I can't see how you are not 
ending up trying to mount the components upsidedown.

JaMi's process (different from yours as it does not do the 'L', but does 
other steps) works.  I can't see how yours does. I would love to know.

Bye for now,
Ian Wilson
