Due to server lag i had to click a dragonscale expedition flag multiple times for it to finally activate and it gave rep with dragonscale expedition for every click.
Not sure how repeatable it is, since it’s due to server lag.
Please delete what happened as others could copy it and thus it could be considered an exploit. (Not saying you were exploiting just that others will do it deliberately).
