I have played SDV on PC, non-modded, on several files and never had an issue with the flute block mermaid puzzle. This is my first Switch play through, and I place the blocks below the designs, but when I walk past them, only three out of the five blocks play. I made sure they were all facing the same way. I must have checking the tuning a dozen times at least. But the tuning isn’t the issue - no matter what I do, the second and fourth flute blocks do not play, even when I turned off auto-run. I want the mermaid to wave at me. And I want those walnuts.
