I’ve been trying to get credit for the moa event for a while now. I’ve tried pretty much all that was recommended above, to no avail. However, as was pointed out, since there is no stopping at all, I’m not sure if I’ve managed to kill anything, but I don’t know if that’s what it is. On all tries there have been a mix of people saying that they’ve either got the achievement, or that they haven’t. As I’ve been guesting to Tarnished Coast to play with friends, occasionally being put in overflow, I’ll try a final time on my home server to see if that helps at all. I hope that this can be fixed, or maybe I finally do something right, because it’s really disheartening to complete the event multiple times, only to not be told if the event completed or failed.
