I also saw a video on Youtube, and yes..I think it's bugged.
I'm with last chest. The very last one near the stone stairs to church's entrance. I took all keys, but it's still locked.
I had same problem with the second-last chest, but I quitted the game then reload, and it worked.
With this one, it doesn't work. I also tried to teleport from another location, as support said to me, and still nothing...
Any tips or cheat the open the chest?
