Tags Dissapeared - Root Cause?

[Skellerman]

On my project yesterday there were two individuals tagging wall assemblies in elevation all day. The tags and sheets were in a core building model and the walls they were tagging are in a linked shell model. Throughout the day they were synchronizing to central and the information saved just fine. At the end day they syncd and all the tags were gone. My first inclination is that it was user error and someone selected all the tags in the project, deleted and then syncd. However, I want to make sure there is not some fatal flaw in Revit 2013 that causes tags to go bye bye. As anyone else experienced this?

I re-tagged one elevation to investigate why this might have happened. I then unloaded the link, syncd and then reloaded. Tags were fine. I closed the linked file workset, syncd and reloaded. Tags were fine.

I'm still leaning towards user error but want to ask AUGI members if anything similar has happened?

User error. If you are bold you could go back through journal files to figure out who did it, but I am not sure how productive that would be. You could also look through the backups to see when the last version that had the tags existed.
In my experience, Revit does not delete things without warning and in this case I would think that if something was going wrong with tagging a linked model, the tags would be orphaned at worst (appear as question marks), not deleted.

No more than two hours ago, I exploited one of Revit's weakness (I know, they're hard to come by) to restore an Electrical Panel that was rehosted and lost all of its circuiting. Purely disastrous at this point in time (no Undo available). Anyhow, what I did was have the guy close without saving and relinquish elements. I opened my local file which was created moments before the disaster, I move the panel 1/256" to take ownership of it and Synched. The panel was restored on the Central Model, effectively undoing his work.

The reason I bring this up is that by chance someone took ownership of that View with their older Local File after you Synched and then Synched themselves? Thus, writing their version of the View to the Central Model, which had no Tags.

Thanks for the good responses. Considering the tags were deleted from multiple views it probably was not a ownership issue with sync times. I will keep the journal files in mind in event of serious misfortune. Thinking out loud, I wonder if it is possible to use the journal files as a way to maintain accountability if using Revit server.
