[2023] "/build road" commadn not fully fleshed out? Or am I using it incorrectly?

Hi all!

According to the game, the /build road command is used like this:

/build road length (Int32), width (Int32), buildTypeVal (Int32), bottomType (Int32), flatRoad (Boolean)

However if you try this, only length and width seems to work. buildTypeVal and bottomType don't change the road from dirt, no matter what's used... Neither the old /spawnroad method (1=Stone, 2=Concrete), nor using the itemID of the material you want to use.

flatRoad does work. If I set the fifth item to True or False, I can make the roads be flat or follow the terrain. But the third and fourth variables don't seem to work, and the roads are always dirt.

Am I just using the command incorrectly, or is the command not fully fleshed out/working?
