Guild Wars 2

the bl jp’s do bug out sometimes, I had this happen on the garnet one. Try doing it on a different toon

thats ok, you get upscaled for wvw, you can simply make a new character, go through the first mission and go right into a bl to do it

aside from that, this has been a longstanding random bug, it happened to me over a year ago, so yea..lol I doubt its gonna get fixed anytime soon. Can either try making a new toon to complete it, or just wait a few days and retry it again. Good luck.

yep, was bugged on my ele, got it on my thief. Also just a side note, you can use the same keys on a different bl jp. So say you get the key parts in sapphire you can use them on emerald/garnet.

happy to help, hope it works out for you

yea find them again

The parts of the key are shared for all three borderlands, making it possible to retrieve key parts on one borderland and open the chest in one of the others. It may be easier to collect the key parts on your own borderlands to use on the other two. However, you cannot collect a key part more than once per day on any one borderlands.
You need the key parts to unlock the door and chest. While a person with both key parts can open the door for players without, each player requires both key parts to open the chest for themselves.
If someone opens the vault for you, you can open the chest, but you will not receive the achievement for having done the jump puzzle, and if you do the jump puzzle before the chest resets; i.e. right away. You will be unable to complete the achievement until the chest resets for you.

Found this on wiki, might help out, if nothing works atm, you might have to wait till tommorow to try again
