Can confirm it still exists in 1.12 as well. I can provide photo's if needed.

It has the exact same symptoms. It has happened to me on a lan server and it has happened to a friend on a actual dedicated server while I was on. The reproduction steps are the same but it doesn't seem to work most of the time. It doesn't go away after relogging. I have pictures showing it's still not fixed in pre7 if you need them.

It goes away after dying, not sure about relogging.

It works on every computer and server with minecraft 1.9. Why don't you actually test the bug for yourself so you can see for yourself. Even Slicedlime said in one of his videos about this stupid bug.

Are you sure the teleporting to a spawn chunk and back will work? I have a perfect system to make you invisible, so I'll test it.

Everything does damage to them except melee combat from other players.

While in this invisible state your also invulnerable to other player's damage.

This bug is currently in 16w07a as well. By the way I know how to replicate the bug. It has to deal with loading chunks on a server. If someone loads chunks by using TP command they will become invisible most of the time. If a second player teleports to the same chunks the first player is already at the second player will not become invisible because the first player is loading those chunks. That's all I know and I can replicate on my server very easily.

When you setblock/blockdata a colored sign on singleplayer everything works fine until you close the world and load it back up, then the sign is completely blank.

Also some sounds don't work when you in the bug like fall damage and burning in lava.

This is a common glitch on 1.9 servers and if you want to know if your one of the invisible then some sound effects don't work. For example, falling in lava & jumping from a high place with that leg break sound doesn't work when your invisible. When we mean invisible we don't mean by the effect, but as in the fact no one can see you. The only way we can get people to get out of this state is if they re-log from the server. I have tested this on many different servers and different snapshots so the bug has been here a while and is real.

I mean there are better random generators out there in minecraft. AKA Armorstand random generators.

I strongly disagree but you can have your own opinion. You might be thinking of a different armorstand random generator than I am because the ones I use are actually really compact and are multiplayer friendly at a great scale. I would highly recommend to go look at that guys channel.

The MOD did say it was a bug so it will be fixed. I recommend using armorstand random genenators which are actually better than dispenser ones. shanewolf38 has some good tutorials for them so I would check them out.
