I'm doing adventures as often as possible, which means probably one most days. Recently I've been doing Stealing from the Rich which used to give quite reasonable amounts of granite - not amazing, but reasonable. But now you're lucky if you get 200 every third time. That can't be right. At that rate, it will take a month to get enough granite for a Damascene weaponsmith, not to even think about upgrades.
This is unacceptably slow. Please sort it out.
