There is a bug in PC Version 1.61 where the skills don't save when you save the game. I just wanted to make sure this bug was noted so when Craig gets time he can fix it because I love the skills in the game, (in coming rant) they make doing anything in the game much more fun to me because when you level up you can do things better and you have to unlock crafting recipes instead of just needing the materials to build it.
I just love RPG elements in sandbox games.
