Dammit!
I made a mistake so I will be releasing a patch soon, hopefully today. I will probably include a couple of things I was saving for the next update.
I just noticed liquids cannot be used as a component in the construction window so you can’t build walls right now. To fix this, I will be adding a new item:
Mortar Plaster
"A workable substance similar to a paste used to bind other materials together and fill gaps between them. It can also be used for coating walls and ceilings, making this building material suitable for both finishing and load-bearing."
To make this, you need a Sledge Hammer to crush components into aggregate or filler, and a Trowel or a Shovel to mix it all together. The components you need are 8 lumps of clay, 3 rocks or 30 pebbles or 6 bricks or 30 bones, 30 units of cement and 3 units of water. You will get 60 units of Mortar Plaster, which will be enough for 5 walls.
Also:
-Bricks will require a bit less lumps of clay but 2 units of water.
-Walls will require 12 units of mortar plaster and you can use 7 units of superglue as an alternative to nails for the panelling.
-Ability to make concrete walls, which will require a lot more mortar plaster instead of panelling.
