Guild Wars 2

There are some ways to run the GW2 client multiple times, you might try Google,

And this is what an Anet mod sad about playing with multiple accounts/multi-boxing, (7 months ago)

Juist done Tequatl the Sunless and the Shatterer, both times no chest.
There can be no DR because I was afk for 2 hours before it, and i did both of the dragons on a other character.

I only have this problem at the dragons, all the other chest still spawn for me.
So this means that DR or the chest is bugged at the dragons.
