Makes water a finite resource. Uses a depth map: each water tile has a depth based on its type. Pumps drain lakes; depleted tiles become land. Refill with outfall pipes and rain
Large total conversion mods.
Map generation and terrain modification.
Things related to oil and other fluids.
Changes to power production and distribution.
I'm having a lot of problems with lag. I can't remove the calculation of tiles that don't belong to a coastal pump.
You can try installing an offshore pump again on that water body and then removing it. This should help.
Could you please describe how this situation happened?
