Guild Wars 2

That’s what I was doing. I relogged into the mini game and it’s counting up now

Hello I’ve just spent about 1h trying to get this achievement and I must be doing something wrong because my counter still says 0/1. When I mouse over the tool tip says Stop gift bringers in snowball mayhem. So I did this for a bit I down them but nothing happened, then I made sure to finish them after downing them still nothing happened. I’ve even tried unsuccessfully to down them then finish them and finally take the gift back to our base but still the counter sits at 0/1 mocking me for not doing the right thing to trigger this achievement.

Can anyone point out what I’m doing wrong?

Thanks in Advance.
