I was one of the people who logged into the Karka event and crashed right before the ancient Karka boss thing died. So I never got my items. I submitted a ticket, posted here on the forums, and waited.
…Today I log in and there’s an Ancient Karka Box in my mail inbox. I open it up and find my inventory filled up with yellows and oranges. That really made my day, and I wanted to say so here, publicly, because it seems to be so rare that the GW2 devs get thanked for their efforts.
