Gold Rush is a joke as a quest. It takes hours. Today played for over 2 hours and zero wins that the quest was asking for. This happens all the time when you require Gold Rush. Either that, or make it realistic to accomplish.
I agree, sometimes it is extremely tedious. However, I've found that sometimes, if you go out, play another game for a few minutes, and then go back, it's "friendlier" for some reason. Just my experience.
