Guild Wars 2

Can you guys please explain to me why this is acceptable? It’s been a solid 2 hours and farming coral on 3 characters is so repetitive and feels so un-rewarding. So far i’ve gotten 0 of this and i’m about to just give up. All this gold i’ve drained into this precursor and this has been the only issue so far.

Can someone please tell me a way to get these vials? Magic Find? Boosters? RNG Luck?
Please?

There’s been a bug that’s been going on for quite a bit, and i’d like to inform Arenanet about this topic. I just started playing Guild Wars 2 again and noticed the bug again.
When a human female laughs or a norn male laughs, multiple laughs from one person can be heard.

Here’s an example I saw on a related forum.

I see other people talking about the same problem, so it can’t be just myself.
Other people are saying it’s some of the other races as well.
