I have a very simple rig with a central control null, that I've turned into an hda.

The bones are no-IK bones, since I only want rotations. The central null is used for translating the whole character.

I've promoted the appropriate channels to the top level of the asset.

When I first bring in the asset and translate the character, the parameters don't update. Yes I have Auto-Updating turned on.

If I navigate down to the next level and manipulate the null handle, I can see the parameters updating. If I then come back up to the top level the parameters are now updating properly. This is without making the asset editable.

Am I missing something or is this a bug?

I'm using the lastest build.
