Guild Wars 2

So for the last few days I have been attempting to work on the precurser for The Predator legendary and this even has been stuck. I’ve watched videos and read everything that I can find but I can’t finish or restart it. The npc’s won’t respawn and everything seems to be done that can be done. So how does one go about fixing this? I wouldn’t normally complain about such thing, this however is what i’d decided to do since Mordremoth is bugged on me to and he won’t drop below 18% health when the fight freezes after the second wave of shadows.

Any suggestions?

Try again after a map reset.
But dont expect to finish the quest chain and get your collection part, there are still more bugs to stop your progress:

Anyway, good luck
