Ardour3 automation import

Hello, sorry if this has been discussed before. I have an Ardour2 project with several tracks that have pan automation. When I open that project in Ardour3, the pan automation is gone. Ardour3 brings up a log that says something about how there is automation with no automationID. Does Ardour3 not support the automation info from Ardour2 projects? If so, why not?

Panning was completely redesigned in Ardour3. The panning automation data in an Ardour2 session makes no sense in Ardour3, and so it is ignored.
