Here is the history of a question I tried to edit.

I first clicked edit on revision 4. Then I added the tag because it was correct. I then saved it.

What happened then? My edit... didn't do anything at all!


What did I break? What happened?


It appears I must zoom out a bit to clear some confusion:


To summarize: my intent was to roll back the change made to the body text by the suggested edit while preserving the change made to the tags. While the tag change was kept, the body changes were not rolled back!

    Did you make the same changes as revision 5? If so, and given the timing, it's a simple edit clash.

  • Yes, adding a tag is a radical change. /jokingSarcasm

    FWIW: I reproduced this. I'll try to elaborate on why it happens at some point, but for now the evidence is in the revision history here.

  • @David How does something become un-reproduced?

    @Doorknob we're not using status-reproduced any more, since it doesn't mean anything has actually been resolved. Comments capture the "We've reproduced this" adequately enough. Commented Aug 17, 2013 at 2:50
  • @DavidFullerton looks like the dev team is not familiar with the decision to not use the status-reproduced tag anymore. Personally I'm against that decision but it's your call. Anyway, think you better nuke that tag or blacklist it so the devs won't get confused. Commented Jan 30, 2014 at 12:44
  • @Shog9 Something just like this happened on IPS today.

You've come across what I'd call rather strange behavior, but I'm not certain that it's necessarily a bug. I'm calling it Schrödinger's Revision

It appears that you were trying to roll back to a previous body revision while preserving tag changes. However, since all you changed was the tags, that's the only post history record created.

Since it was identical to the current set of tags, nothing shows up in the revision history. Hence, it was a revision, but wasn't a revision, and seemingly isn't a revision yet it is. But hey, it wasn't caching!

We're looking at it. This is a rather strange edge case, we are examining it to see if changes need to be made, if only to be made more obvious.
