the battery doesn't appear in the circle in the first location

Nice game, as usual! I'm wondering how to get the "Autumn is in the air" achievement? I finished both playthroughs and returned to the deer room many times, but the autumn leaves still don't show. Any idea?

Despite playing the game three times, I did not get the last achievement. The last scene does not appear. Any tip?

Can anyone describe how the answer to the tree puzzle works please? I checked the walk-through for the answer but I still don't understand what is being counted and why there are 2 versions - one with and one without a surrounding circle. Thanks! Further to my initial question, I've now figured it out if anyone needs advice....
