Guild Wars 2

So I have tried doing the WvW Supply Lines Guild Mission in 2 different guilds, three times. Escorted 8 yaks successfully, but did not receive the reward. This has also been effecting other players in the guild who helped escort yaks (3 player minimum on the yaks) but still no reward once completed.

Did you let the timer for the mission run it’s course? Iirc you get the reward upon the timer ending once all criteria is met.

Our guild has succesfully completed this mission few days ago and recieved reward. Make sure you are close to the dolly with 3+ that are in the same guild. All 3 players should receive the event complete icon after a dolly escort to make it count, this means you cant jump in just before the dolly will deliver its goods. You have to stay with it for some time to make it count towards you progress. Also it has to be done within the time limit obviously. You can check if you already recieved its reward by pressing G, 3d Tab Missions and check if the small chest icon is opened or closed.
