When updating my Mods it skipped over This one and when manually telling it to specifically update the mod then i get a Notice "There is no compatible version of Wood-Walls on the mod portal."
I didn't see that wood walls requires Factorio 2.0.33. It doesn't actually require it, but the author marked it like that anyway. I think you need to downgrade Lignumis until I have a better idea or Wube releases the next stable version.
