0004286: Removing a well makes water undrinkable even if it was drinkable before the well was built
A well is a valid water source only for Drink, not for Give Water or for Fill Pond. Also, removing a well makes that square no longer a valid water source for anything, even if, before the construction of the well, it was a valid water source for all purposes, and the only thing that's changed is the construction and removal of the well.
1. Near an undrinkable pond, create a minimal water tank consisting of a constructed floor, 7 constructed walls, and the business end of a screw pump. Of course, the other end of the pump must be next to, and facing towards, the pond.
2. Build a ramp so that dwarves can walk on top of the wall.
3. Operate the pump to fill the tank.
4. Notice that you can place a valid Water Source zone over the water in the tank.
5. Build a well on top of the tank.
6. Deconstruct the well.
7. Notice that the top of the tank is no longer a valid water source.
No tags attached.

Actually it's a lot worse than that. Water source zones and wells that used to be valid become invalid for NO REASON AT ALL. This has happened to me at least 5 times, and each time, the only thing that's changed is I drew a few bucketfuls/drinks of water from the well or water source, then pumped more water into the cistern. The cistern always consists entirely of constructed walls and floors.
