[Bug] Flowers for Jingo

Just tried to do the achievement - all went fine with escort until Jingo reached one of the cairns that are used for the heart nearby and there she stopped, not moving any further; there's no dialog options, she won't move and she won't progress the event further.

Managed to finish on the second try - it might be that it bugs if Jingo misses a location

I've noticed a ton of places where an escort NPC will appear as if stopping dead, saying nothing, appearing to do nothing. In other runs, I discover they were supposed to be speaking but the audio appears not to kick off or something. She talks to her son in that one you mentioned, I think, and then continues onward. Sometimes that audio fails to kick off, which might be a sign/symptom of whatever controls it not kicking off to tell the audio to play.

In my initial run she stayed in one place for quite some time without doing anything; I've even tried to lure some monsters, to try to unstuck her (as whenever a monster is nearby she will run towards them) - needless to say without any luck.

In subsequent run - yes, she run toward her son and entire quest finished without further problems

Im stucked at the part, when she needs to talk wiht her son during the escort, and i need to whitness it. But either Wazi wasnt there (stucked in texture maybe), or they did speak but the achievment didnt progressed for me. Its gonna be the 4th time im doing this escort, hopefully finally ticks.

There are so many events in GW2 that bug out all the time and have for years. I know that Anet doesn't like to go back and fix old content, so maybe they can fix it right when it first comes out so the game doesn't look so broken.

And as for not fixing old content, new players often go through old content first. I would be hard pressed to convince someone to stay in the game if they had trouble getting through core Tyria because of all the bugged events.

So it turned out that i dont need to witness their conversation during the escort event. When Jingo finished her mission, she comes back to Wazi to talk wiht him again, and i randomly witnessed it while camped there. It wasnt really clear, beocuse in the convo she says, join me on my next escort or something like that. Anyway i could finish it up after that without any problem.
