I clicked on "go to next edit" today (2 June 2018 07:00 UTC) and an edit dated 27 May 2018 popped up. Diff: 843184000 article Lucy Durack. I definitely got the from clicking on "go to next edit". This seems rather odd. I can supply a screen shot.
Ah yes, that's a new feature that is enabled by default. When you revert someone and they have some top revision edits in their history, huggle will download them and add them to queue, even if they are often old.
Idea is that when you revert someone, that someone probably makes bad edits, and the chance is they made a bad edit in past and it was overlooked. It's in preferences -> feed, you can disable it if you don't like that.
