One of the cities in my region has over 100,000 inhabitants and at some point I noticed it had ZERO water usage. City advisors will complain and buildings will dilapidate if I actually remove my water system, but with even a single water tower I get all buildings showing up as watered and no water consumption in the graph. I even tried obliterating the city and starting over and this tile still doesn't use any water. Every other city in the region consumes water normally. I have no idea what to do to get back to normal. Has anyone else experienced the same problem?
Take a look into your plugins folder. Maybe you have some unwanted No Water Usage mod. I don't know if such thing exists, but I guess it does and that you have installed it without remembering...
Thanks, but that wasn't the case. All the other cities in the region consume water normally except for this single tile.
