Guild Wars 2

What portals are we supposed to close? I did the portal events in invasion, 5 in a row in about 10 minutes twice but i didn’t get the achievement? I counted the completed events and watched the world event countdown for time. Are those different portals? Or is it not working?

I would also like to know this. I closed 5 in 10 minutes, got bronze or higher awards on each. Do we have to get gold for all 5?

Or do we have to get all 5 in the same wave? Or does only the main server count?

Edit: Just got it after 13 minutes, all silver or higher.
