Guild Wars 2

I did clock tower yesterday and i got my reward. But now, no matter how much time I get to the end I end up like this. http://www.youtube.com/watch?v=EidpOW2bFWA&feature=plcp
I can’t get inside the tower..

I don’t think it’s a bug. I think it’s an intended stealth change.

Yesterday I completed it a couple dozen times, never missed the final jump. Today I managed to reach last jump 4 times, all 4 times I didn’t manage to enter the window and I just fell below.
They’ve probably ninja-patched tonight so that you cannot enter anymore if you’ve already completed it. So lame
