The October 7th patch introduced a bug at the jumping puzzle within all Borderlands, making it impossible to be completed (the Vault door won’t open, even if you have all the keys). After yesterday’s patch, the bug is still there. ArenaNet very rarely updates the game more than once a week. Ergo, it’s likely that this bug will still be there for some time.
To those going to reply, “So now people will play WvW instead of jumping puzzles!”, you need to get a clue. The Borderland Puzzles are an important source of siege weapons; if 5 players did them, that would be 10 more siege weapons for your server, which is far more than what most of those reading this have ever bothered to buy themselves.
As a bug introduced in a very recent patch, and as one more bug to the already filled with bugs WvW, this should be fixed relatively soon.
