I will be 100 before I'm able to complete this game and that's not a good thing! Why? Things take forever to 'complete' in the craft hut and if you only have 1 of 3 spaces....well, you get it. 300 stones for the 1st upgrade and 600 for the 2nd, meaning I will be about 100 before I complete this game. Should have considered that when changing from app to PC form. 10 lavastones a day STINKS!
