Since the village and pillage update, villagers don't know how to share doors! If two villagers try to leave through the same door they both spam the door opened and closed. Not only is the sound very annoying, but if you are trying to build a village then it makes a larger city almost impossible! My proposed solution: manners! The villagers will not try to open and close the door over each other, but civilly let each other through the door(s). Villagers sometimes act like cartoon characters that all try to jump through a door at once. Please fix this, as I assume it is a bug.
