Why is my action getting higher?

Haven't had to adjust the truss rod in 15 or 20 years until now.

Have gigged the 360 a bunch.

Oh, the nut on the left wasn't tight either.

Masking tape appears to be, "MA" There's "25" written in red below it.

It's that time of year... weather! I have to adjust all my guitars at the beginning of every fall and spring, even when I lived in Florida.

I think you misunderstood the nature of the picture.

One truss rod nut had vibrated nearly off the truss rod, the other was loose as well.

That doesn't sound too concerning, it just means your neck is already pretty stiff without a lot of tension on the rods. If you tighten them up a smidge beyond finger-tight it will probably resolve your issues.

Well, I get it. (Pretty cool.)
