I just updated today. In my first world, a few days ago, I couldn't find a mission with the first building in it. So, I was happy to see one this time. I completed the mission, but found I didn't have enough granite to build it. That was odd since I did several other things before completing that mission. I can now not find granite anywhere. I've tried several biomes and went through many, many caves. The only granite I did find was just the outcropping in the tutorial area. I found plenty before the last update (but could never use it). Anyway, did something go wrong or am I just super unlucky? I've also seen no iron/copper resources even after those were unlocked.
