I have been playing on my farm for some time now and in the collection, it says that I have all artifacts and minerals for the museum but I have not gotten the achievement nor have I gotten the stardrop could someone please help me. Here is a picture of my museum if someone sees what is missing please help.

I don't see the third doll (the yellow one).

Because I'm bad at searching and that might not be it, if you're on PC you can upload your save file to the Stardew valley checkup (https://mouseypounds.github.io/stardew-checkup/) and it will tell you what you're missing.
