I took a drink from a well, a short while (about 10 seconds) after I had a drink I needed another one despite saying my thirst was quenched. I ignored this one. Then when it became incessantly annoying i tried to drink from the well again. The option to 'Drink Water' is there but nothing happens when you click on it. I would test out drinking from a container but there's simply no food or drink or containers anywhere right now.
Also when you drink from a well it says "you took a drink from the pond"
