I recently achieved two daily goals at the same time. When the prizes were rewarded, it showed two iterations of 1,000 gold. (not due to my mastery pass, I just completed level 77) My balance, however, only showed a 1,000 gold increase. I don’t know if the reward was mistakenly duplicated on screen, or if I did not receive the 1,000 additional gold. It doesn’t cause me too much grief, just something I noticed to be buggy.
