Guild Wars 2

I completed Viziers tower jumping puzzle but did not receive a chest at the top nor was there an enemy at the top to fight. When I was to the purple mushrooms on the way up I got the acheivement that said I completed the puzzle but I did not make it there on that attempt. I think there might be a bug?

You sometimes have to wait a while before it resets. You don’t actually get a chest until you kill the undead up there. Someone else must’ve killed it before you got there.

yes. I went back in today and it was there. Thanks
