Guild Wars 2

Kill Bria quest bugged – Bria never shows up to start fight
Escort Sentinel Scalebrusher and his devourers – They’re eternally fighting an Annoying Flame Legion Shaman who’s standing on flat ground not moving and is invulnerable. You can’t get them to stop attacking him to start the escort.
Kill the Flame Legion Shaman boss – he never shows up
The quest to release the dogs, attack the trees they’re barking at and then kill the separatists that drop out – dogs bark at open ground with nothing around. None of the trees are listed as “Suspicious Trees” or anything like that. Someone else who had already completed this quest came over and told us to just shoot or hack at random trees until separatists drop down.
Under the dog/tree quest is a cave with a quest to help raid the area. Go down there and two NPCs are running in circles but you can’t interact with them and there are no enemies down there. I’m only about 1/3 of the way through this zone and nearly every quest is bugged so far. Chat says other zones of 50+ are even worse.

The Kill Bria Dynamic event is bugged for me as well.
