So you unlock the moss blanket and overgrowth, then you read the starmail you get from Ogden after that, then you will have a teleporter in the overgrowth halfway there leading to Ogdens retreat, then you talk to him two times through the trading machine in Ogdens retreat and he'll activate the teleporter leading there. Thats how you get and find The Wilds.
Is your game up to date? We're currently on 1.1.2.
The main reason we get people saying they can't get to new features is because they haven't updated it, and is on an older build. The game should tell you on the main title screen when you open the game.
