You can't build the factory on ores, you are need to remove it before.
Compatible with all mods, works in multiplayer and costs no extra UPS.
(added 'resource-layer' collision mask to some buildings).
I just download your Mod and started a game but I cant build a water pump to get water to my steam boilers so I can have power. It says I cant build on water or grass. there are no boxes where you can normally build the pumps.
Thanks for report. fixed!
I have modded offshore pumps and here was no problem with it.
