Oh snap, I thought that button was to open the dang thing, not something else. Even knowing it was there, I looked, didn't see it, opened the chest and figured it was one of those automatic things. Seriously, those buttons are too hard to pick out from what they are on. Like the one in the battle tower before you fight Laiken to uncover the explosives ... I searched for that for hours, even knowing it was there.
Of course, the other flaw is that highlighting something you can activate is way too wonky. It's very hard sometimes to get that sweet spot to activate.
