    That is really strange.
    Too much humidity will possibly make metal parts start to pit, but the gold just disappearing, I’ve never heard of that.
    I hang my guitars in large hanging wall cases. I run a humidifier in the room. The evaporative type. I’ve never had a problem like your having.
    I’ve never really understood the science behind the humidity packs that rely on osmosis to work. So I never would leave my guitars couped up in case with those packs for too long.
    Sorry about this issue.
    I’d be seriously upset if I were you.
