Can't make vertical slabs and vertical slabs can't stack
The forge modpage says "Simply hold sneak when holding a regular slab to place a vertical version! This also works with combining two vertical slabs including vertical slabs from Quark, just ensure you are not holding sneak to combine!" However, when I tried placing down a vertical slab with Sneak, it just placed down a regular slab, and when I tried stacking vertical slabs from Quark, it didn't work.
I also have this issue, i also can't give myself a vertical slab in 1.21.1
In the 1.21.1 version, vertical slabs are a separate item crafted by putting a slab on its own into a crafting table. (The mod page does mention that the sneak thing doesn't work on 1.21.1, but that may have been added after this issue was made.)
