Copy Pasting a glyph without components:
Did you do anything when you were editing the H?
No this happens every time. I just closed the doc and re-opened it. Happens even without the H beside it 
Can you send me the file?
there are some leftovers in the userData of the nodes. Run this script to remove it:
for p in Layer.shapes:
for n in p.nodes:
del(n.userData["GSSegment"])
Or the Garbage Collection script.
The Garbage Collection script does not remove these leftovers in the userData, like Georgs script does. Or am I missing something? @mekkablue
Would be nice, if it did though…
