If the desert isn't available yet, then at least how do you get to the deserted base?
Also why do they have to post other updates on Patreon. I have a account but, I can never find where you have to go to download.
The way I found the deserted base was in the Wilderness outside New Ark City, where I was traveling to and fro from Transylvania, the city, and the abandoned town. During all that travel, there's the chance that you find two secret places: the Milk Farm and the Base. The screen will blip for a moment, and you'll know that you found something.
