Missing node setups in 2.8

I opened a project originally built in 2.79 in 2.8 and two of the three node setups aren’t showing up. I had one for the walls, one for the wooden frame and one for stone blocks and roof tiles. Only the walls node setup is showing up. I tried texture editor and there’s nothing there ether. I’m pretty sure the other node setups are there someplace, I just can’t find them. Any suggestions?

Node setup as in material? If it wasn’t assigned to an object when you closed Blender, it won’t save (unless you hit the little F).
