I have 15 points in the Production skill tree. I was hoping that the last update would fix this, but it didn't. All the other skill trees have an amount of points to gain another skill. My production skill tree has zero points. I was thinking that if I could get 600 more points in Herbal. Then I could get the potion of Possibilities and reset all my skills.
Also on a side note, don't Bears hibernate in the winter? Other then that I love the game.
