In the top 5 stern post, I posted once, but it re-posted so there were 4 duplicates of the same thing. Replicas had 3 duplicates in another post recently I saw, so this is not a unique problem.
In the Stern post it now won't let me edit all the duplicates. I edited two, but even though the edits were made in posts 3/4, it actually updated posts 1/2 (changed them so they just contained full stops). And see this screeny below....I'm editing post 3, where you can see my list of four pins in the original post, but the 'edit post screen' just contains the full stop from posts 1/2. No matter which of the 4 duplicate posts I choose to edit, when the edit screen opens it just has the full stop in it...so posts 1/2 cannot be edited.

Edit: posted from my PC using the latest version of Chrome - same as ever.
