The only additions to my changes list today are your two edits to your own Guernsey fleabane observation (the one with the long comment trail). (iSpot has just decided to fail, preventing me looking at the two observations you mention, not that it is strictly necessary.)
The favouriting of the first one hasn’t shown up in my changes tracker, though I would have expected it to. Possibly because there were no actual differences between successive runs of the changes tracker.
