? This is not a problem at all; it is working now.

[jar398]

Excellent! I was just copying the issue over from the feedback repo. Will close both issues.

Note that v2 would return the tree of valid ids as well as list which ids are bad. The v3 does not return any tree if any of the ids are bad (it just tells you which ones are bad).

Yes of course I know that, I'm the one who made the change. The problem has been under discussion for a while now, but there hasn't been an issue for it, so I just created one: #226

[josephwb]

I believe I made the change, but regardless I was just making sure that this was still on the radar.

We both made the change; you did it in treemachine, I did it in taxomachine.
