Post-Invasion DE Reward Bug
You hit DR. if you do more than 25 events in an hour you no longer get experience and karma for those events.
You will need to log out for at least an hour (or just not do a single event) before it will reset completely. As long as you are above the 25 in the last hour mark you will not get rewards.
That seems like lack of planning on Anet’s part.
You don’t win friends with Salad.
This is what I came in to ask as well. The log out for an hour suggestion doesn’t seem right… when I logged in this morning after waking up, I was still getting terrible event rewards from the Maw (which I hadn’t done today). Maybe it’s an hour of game play. I just did a dungeon and now I’ll try idling in DR… maybe that will clear it up.
