From what I know, this bug works all the way until snapshot 18w10d. It has been coined the phantom nether. i have tried it and it works. i do not know when it first started however. i guess as long as you could place portal blocks inside the end.

The main problem i have found with this post is how bad the grammar is. But besides that, the phantom nether can also be fixed by going back to the overworld and to the nether again. This is a better option for multiplayer as leaving the world when you are not the host will normally do nothing. You can also go back to the end first just in case. I suggest making sure no one is in the nether when trying to fix this bug (it doesn't matter if it is the phantom or regular nether). You can also try multiple other things such as Mcedit, however, I do not know how they would help. But, I don't use Mcedit so I could be incorrect.

Technically players are entities stored as Player which is why they are affected by the @e tags and [type=Player]/[type=!Player] work for them. However, unlike most entities, Players cannot be summoned with mods, commands, or external programs. Instead, a real player must join the game. You cannot edit their data with commands in all the ways you can with nearly every other entity. Here are some of the things you cannot do without mods, addons, plugins, or changing code: custom names, make persistent (this is because players do not despawn unless they die), and disable ai (this is because they do not use ai since real people control them). Some things you can do include the following: effects, execute, kill command, tp/teleport, and making name tag show up or not show up (depending on whether you have them highlighted or not). You can edit more things by editing files such as invulnerability, can fly (regardless of gamemode), is sleeping (weird things might happen if you are not in a bed), disable or enable exhaustion (exhaustion means drowning), etc.
