Guild task no rewards

What you were expecting to happen, and what actually happened?

Today while I was offline my guild completed brown task lvl 6. So when I returned I was expecting 180 gold keys in my mail, but there was nothing.

What are the steps to make it happen again?

Not sure… Ive marked the progress of my guild’s tasks and in case there are any more rewards I will be missing in the future Ill update this post with the details.
