This is just too much... This can't be right...

Yesterday's Time Quest gem was 11,200, and today it's 500. Seriously... I knew the 11,200 gem was a lure and would drop right after installation, but I thought it would go down in stages, right?! The 11,200 suddenly dropping to 500 the next day?!! There's no hidden condition, so a sudden drop to 500 the very next day is just too much.... This is really pushing it...
