Guild Wars 2

So normally I farm the Clock Tower for the Trick-or-Treat bags however today I am not longer able to get into the glass window. Now I know something is wrong considering I make it to the top every attempt and had no problem but now I never get the loading screen or my face smashes against the glass. What is going on here?

i had the same problem like you.
now i jump way later than i used to and it works now (for me)
