Hi, in all version of L8 paste time does not paste automation. It works fine in all versions of L7 that I have (those up to 7.14)
here you can see that automated macros "cut-time" from bars 0-9 and "paste-time" to bars 9-17

it took me a while to figure out what was happening here.
I've ruined a few arrangements with this one I think!
