Guild Wars 2

So I make sure I complete the jumping puzzle once every day, and have gotten pretty good at it. But… 30-50% of the time, I get teleported back to the spawn when I don’t miss a jump. The last time I did the puzzle, I got all the way to the final present before you jump into the big gift and got teleported back to spawn. This makes it so I have to spend almost a half hour each day doing this puzzle instead of one easy go at it. Is there some reason this is happening?

This happens to me all the time in JPs, be it the Winterdays one or the fractals ones. I reckon its the lag, i most likely ran over the edge in reality. Whats weird is it only started occurring recently.
