Vertical Slabs Compat
Similar to Every Compat, this mods aims to fill in mod compatibility gaps by adding Quarks vertical slabs to all blocks that have a slab.
This work automatically and won't register ones that are already there
Altho it adds stuff for Quark the mod itself isnt required and you can also use it as standalone
This mod only purpose is to add vertical slabs so don't ask for vertical stairs or other micro blocks like crazyness like that. If you want those I suggest using this mod here
