Mod is a dependency to freight forwarding, so disabling it kinda does not work.
When placing landfill on shallow and normal water, the landfill holo is red, as if trying to place it on land. clicking does nothing.
Only for the deep sea it works. Also the ruins mod spawns buildings on shallow water. i also cannot use the explosive excavation mod on it, which is intended as it can only be used on land tiles to turn them into deep, non walkable water
