Crash and Chests
Since you posted this 14 hours before I am posting this reply, my reply is relevant.
I, along with everyone else according to map chat, experienced the same things you have described above. That is until today. I did all of the dragons, Maw, SB, and the Golem, and there was absolutely no lag at any of the events. Yes, there was still a giant zerg at each of them, so the relief wasn’t because of lack of players. I assume something was fixed server-side. Most everyone in map chat shared similar relief from the lag starting today (after your post).
One downside: I somewhat enjoyed seeing everyone do the Fear Shuffle…
Yep, I’ve had this happen to me. It’s frustrating for very long events when you crash right near the end.
It would be nice if the game could remember your progress and reward you when you log in again (with perhaps a timeout of like 10 mins or something).
