Stress disappearing from a song seemed weird, but your post changed that.

Ugh, I feel you @hernandez.ben. It's wild how something like leaving a ring near a heater (or even on a sunny windowsill) can do that kind of damage over time. You just don't expect the tiny, sturdy-seeming stuff to need that kind of watchful eye.

Actually, city inspectors almost never give compliments in my experience. That grading work must have been seriously impressive.
