Weird things happen when you return to the overworld from the end

After going to the End and defeating the Ender Dragon, returning to the overworld brings about some weirdness until you reload the world.

Steps to reproduce:

1. Go to the End

2. Return to the overworld

Side effects:

• Portals no longer work (Nether and End)

• You can't place blocks

• You can break blocks, but if you try to put down a different block in its place it turns back into the original block

• You can't spawn mobs

• You can't collect XP

• If you drop an item it disappears

• Mobs won't pay attention to you

• You can't push mobs around

• Mobs won't make their usual noises, but you can still hear your own noises (block placing/breaking, footsteps, etc.)

• You can still blow TNT up with a flint and steel, but doesn't make the fizzing noise, just the explosion noise. TNT can still blow up blocks.

• The lodestone still works, but it doesn't make a noise

• You can still interact with chests and minecart chests, but again, no sound

• If you try to enter a minecart you get kicked right back out. Same story for boats

• Chat still functions

• The player cannot create new chunks

Temporary solutions:

• Reload the world
