Dear Dave,
I researched the issue database for you and found REVIT-78817 [Changes to "Current Revision" parameter do not trigger dynamic updaters].
Please make a note of this number for future queries.
The fix versions listed there are the next two major releases.
You should therefore be able to download the most recent preview release from the Autodesk beta site and try it out yourself right now.
Please let us know how you fare.
If you encounter any issues with the fix, please discuss them directly with the development team in the beta site discussion forum.
Thank you!
I hope this helps.
Cheers,
Jeremy
