I'm running into an issue with an automation lane that I can neither select or reassign. This is what happened:

• I wrote an automation on my vocal track to a Verb/Delay bus
• I deleted the bus which removed the send on my track.
• The automation lane for that send still shows on my vocal track but cannot be selected with the smart tool. It also doesn't show up as any of the automation lanes.

It's not causing my any issues at the moment but I'm using automation more I'd be interested how I can either reassign or delete it or maybe report this as a bug. Any help/tips are appreciated!
 

I'd try adding the bus back that you removed (same name and location) to see if the envelope "reactivates" itself.
 

Had that happen once and couldn't figure out a solution. Now I delete the envelopes before I delete the send...although as you mention, envelope zombie graphics seem harmless.
