Autosaving causes massive performance drops

Every time the game autosaves, it causes the game's performance to drop significantly. Chunks start failing to load, causing long wait times to progress in the game (sometimes up to 3 minutes). Some blocks also fail to load properly, leading to the player being able to see through blocks. As well as this, the game is delayed when certain actions are performed, like breaking a block or creating an item. Menus also take a considerable time to load when accessed.

This issue also affects other players in multiplayer. Whenever the game autosaves, it causes considerable lag on other players, impacting their game experience, no matter which platform they are on.
