I recently got the "Workflow has been deactivated" email on a sheet that I inherited in a large workspace from a former team member. However, when I went in to troubleshoot the error, I was unable to because the name of the sheet it referenced was gone, replaced by "unknown sheet". It would be much more helpful if we could get the "broken" notice but have all the original parameters visible, either in the workflow or included in the notice. Without that information, I am currently unable fix my workflow. (The very vague title of the workflow doesn't help for troubleshooting, either, but that fix is not in your scope!)
