Worlds hosting multiplayer aren't saved when the game is saved and quit

[CubeGamer647]

I'm not sure if this is the case on servers or if it's just while hosting directly from the game, but I've given it plenty of time to save the world, both in the world and on the menu, and when reloading the world, it is reset to before the world was online. The character does save, however. Tested both with no mods and with only DragonLens,
