Black marble floor costs 4...

[cosmicat]

The "Black marble floor" building object costs 4 Black Marble, but shouldn't it cost 6?

The similar-shaped "Stone floor 2x2" costs 6 stone.

For comparison, both the "Stone wall 2x1" and "Black marble 2x2x1"cost 4 units of their respective material.

Unrelated: I was typing this while in a swamp, and an Oozer poisoned and killed my pen of 2* wolves. May their sacrifice not be in vain.

for comparison, I get more rock than I can carry in about 10 min in the plains. It takes me a couple of days to do that with BM unless I get a lucky farming spot. Mostly I am finding the little columns that give like 25 total for all of them. Ive found one big tower I want to tear down, but I haven't gotten to it yet as getting a stone cutter there is an ordeal and kiting a soldier means finding one ...
Ive spent days gathering enough to do one room in BM with alternating old stone floor for a checkerboard pattern but all the walls etc gonna be BM.

Its probably a bug, and you are probably right. But I can live with it being lower, esp the floor piece, which is what I use the most of.
