Many users have experienced problems with the latest Minecraft update. Some users have even found they can’t load the world.
The good news is, 4J are already on the case.
The save-loading problem that affects Silver subscribers is being addressed. 4J are also looking into latency issues, with reports of poor level lighting and an error that prompts the game to tell people that mobs can’t be spawned.
No word on when the update or hot-fixes will be released, but we anticipate it shortly.
