Homeworld redux just got a update which changed the name of sand to dry-dirt. easy fix.

Just need to change sand to dry-dirt in the special handling for homeworld section of the control.lua (approx line 760).

I've changed it to use sand-1 as tile for sand ore.
I also looked at how it works without RSO and it's strange - you get sand resource on every sand on map... it's like one huge ore patch. It might mean that RSO doesn't generate enough of sand - let me know if that seems to be the case.

Yeah the original version placed it on every "sand" and "dark-sand" tile. With all the tile changes after 0.13 I updated it to include "sand-1", "sand-2", "sand-3", "red-desert-0", "red-desert-1", "red-desert-2", "red-desert-3". For Alien Biomes, it's all the tiles with "sand" in their name somewhere.

On the one hand, sand is used for making glass for wine, which isn't used all that much. Only one tier and it's not a very high requirement.

But it also adds 5 sand as a requirement to making concrete, and that could suck up quite a lot.
