When attempting to connect to a server and then cancelling connection immediately when the game reads "Locating Server", the game performs a unnecessary save and quit, as there was no connection to the server, and no progress to save. this started occuring around 1.16.200 and hasn't been solved since. It's a bit hard to explain but a video will be provided of the bug and a edit of the expected results.

Steps to reproduce:

-Open Minecraft

-Go to servers list

-Connect to any Minecraft server

-Disconnect immediately (When the game says "Locating Server")

Note this bug may be harder to reproduce when using a very high quality internet connection.
