Blast-Proof (Savage and Ravage)
Calcite (Caverns and Chasms)
Polished Calcite (Caverns and Chasms)

All of these mods have other slabs that do not have this issue, and i have verified that this is consistent and applies with only Vertical Slabs Compat, Quark, the given mod, and any required dependencies.
