When i started to play the game I was able to break all kinds of blocks wit the pickaxe, I didn't have to change to the axe for wood or the spade for dirt, the pickaxe did it all, but then that change and now with the pick axe I can only breack cobblestone and other hard ones but cannot break wood or dirt or wool.. I have to change every time and it is annoying. I don't know if I did something or change something... How can I go back to what it was at the beginning ?
