No, if you make money, you are also in charge, and the wealth is flowing out.
Resolution: Place a wooden elephant in the middle of the store above the water flow! Wooden, with the trunk facing down, with or without tusks. Hang a mahogany animal head on the wall opposite the water flow, so that it faces the direction of the water flow.
After the trench project is completed, try to restore the original appearance of the ground!
Good luck!
