There's also a glitch that if the water device is to close to each other then you can't access or leave the cup of water. You can press e but nothing happens.I have to make another can before I ever have a chance to collect the water even though there should be one cooking already.
I don't have an option to build a wall or stairs. I have the base crafting ability but nothing beyond that. Another bug I have is that when the water and food cooking thing are to close together it glitches by not allowing you to cook or pick up what is already there.
