If I may ask ... how does anyone know what's in the chest if nobody is able to get it out and open it?
That's not why. It's because treasure chest contents are listed in the official guide. At least, that's what I read when I was researching the bug.Because the bug didn't happen to everybody. It's a very well known bug but there are people who didn't have the same issue. I know I can't get the chest either. But I do know others who were able to get it.
