Guild Wars 2

I’ve tried searching the forums, but didn’t find anything related to this.
The goal of this dynamic event (It’s very close to Mabon Waypoint in Caledon Forest) is to find the mini animals, deal a bit of damage to them so they turn into an ooze, and bring the ooze to" Zaxis" the golem. Whenever you give one to the golem, another ooze spawns right next to him, which you can just pick up and give to him again, and again, until the bar is full. When it is full, a giant red ooze spawn, but instantly disappears.

Also, you get no reward for finishing it this way.

Edit
The wiki says the oozes you return come out of the golem through a hatch in his abdomen, so maybe that isn’t a bug. But I still got no reward for finishing it, and I tried it multiple times. (Also did this quest on another character a week or 2 ago. Same thing happened)
