Guild Wars 2

For " Lesson: Extinct Creatures" for a collection, say that I have to carry a cub, while killing a risen Gorilla, and I have killed event risen gorillas and veterans and normal gorillas, but I am still not getting credit for that achievement. Is there something I am doing work? maybe some special Gorilla?

it is a trophy, so you won’t get credit for the achievement until you get it as a drop from risen gorillas. this might take some time and a few (hundred) kills.

Ahh okay, I thought I just had to kill them once. Just like the world bosses ones
