Description of bug

When entering and exiting a world it fails to save the thumbnail of the world in the menu. If you re-enter the world while the game is still running it will cause the music to be duplicated either playing the same song at the same time with an offset or playing a different song at the same time as the current one.

I've also noticed that the world loads abnormally fast, much faster than it should be, same for exiting the world.

Steps to reproduce

Enter a world, look around and click the save and quit button. On the world selection menu there won't be any icon or the icon will be the same as before you entered.

If you re-enter the world or a different one the music will become bugged and start playing another song over the one that's currently playing.

I tested this in 1.14.4, 1.12, and 1.9.3 both issues happen in all of them

Running the Game on a SteamDeck on OS version 3.4.8 Build 20230508.1

Suspected cause

It seems to be something to do with how the world is being loaded and saved, maybe it's happening too fast? Not really sure actually.
