In Mod "Undead Legacy" by Subquake, author did not remove jars, but made water a problem that is solved much more interesting. In Undead Legacy the player can draw water from washbasins, toilets, faucets, etc., but there or empty, or is usually a limited amount of water available there, about 1-3 jars. Thus, the player has a lot of empty jars, but no water, but the player can smelt the jars into glass and make windows )
