BINGO!

They were left out and exposed to the sun for too long after being dug up. As soon as they are 'out of their nests' they should immediately be hauled away and out of the sun.

A lot of it happens at the store and at home. Just plain old light
exposure will do it. That's why the plastic bags the potatoes are in
have a solid printed side and an unprinted side. The printed side
should always be up in the store. Get your potatoes from further into
the pile. At home be sure to cover them from light.

This just says light. Not necessarily sun.
