This patch is mainly for building out the structure of the Ice biome as well as some new resource types associated with it (like Ice Crystals and Refined Carbon). There's also new recipes that you can find to make Refined Oil, Refined Carbon (mentioned above) and one other thing that I honestly forgot, so good luck finding it!
I've also added in a new HUB structure that will act as a defensive turret for the time being. In the future this new HUB will have some other powers, but for now it's just a cool building with three floating turrets that kill nearby enemies.
The update logs from here on will likely be in this loose format because of my current time constraints. I've been crazy busy with work and life, so I haven't had much time to focus on development. Hopefully in the coming year I'll be able to make some more time. Fingers crossed!
