I know you said to ignore, but I didn't see the quest description.
Anyway, for the "Craglorn world event" I just did one of the world bosses, but I think (if I understood correctly) some players were saying that those little glowing rifts or portals which spawn enemies ars also a world event. I didn't try that to see if it gave me credit for the quest, but if those are comparable to the little "mini-dolmen" random encounters in base zones, which drop overland jewelry set items just as dolmens do, then it makes sense that they'd be considered "world events."
