This is on PC-EU.
You know how when you approach quest giver NPCs for the first time, they say something about the quest? for a while now, there is this issue where it can play generic NPC exclamations instead. Like the stuff NPCs mention about things you did in the world when you just walk past them. This means they won't say the thing they are actually supposed to and you'll miss out on the first info about the quest. currently, the only way is to go away, maybe even reload in another zone and then come back and try again. very annoying. reported it several times in game with no success. I hope it'll get more attention here.
