So many quests and building upgrades require gold nuggets but with two deep mines, one is new the other stuck at level five and a sparkling mine at level five I have only found two gold nuggets since November. Shouldn't it drop a little more often when it is required to complete a quest? Not having the problem finding shamrocks, diamonds or moss, or any other item in the current quests and challenges, just gold nuggets. With the new challenge, mining the rock outcrop, I found fools gold with every click. Very frustrating that I am unable to complete quests or upgrade the mines and other buildings etc. because I am not finding gold. It really takes the fun out of the game.
