Bug:
I'm in vanish for players who log in after I do.

How to replicate:
If I have been in /vanish at any point, I will get this bug. The player doesn't have to have the vanish join permission node for this to happen. I fixed this with someone by deleting their essentials and world playerdata.

This is consistent. I log in, then anyone who logs in after me won't be able to send me a message or see my name in the tab list, while others will be able to do so.

Extra:
This bug was also there with the previous versions of essentials, before the essentialsX fork.
There are no errors in the console and this happens with a complete default config or a very edited one.

Would it be possible to fix this or maybe even have a version of essentials without the vanish feature entirely?

Thank you for taking the time to read this.

+1 for this
If i use vanish and then unvanish, only players already on the server will see me.
Players logging in after that won't see me and it only gets fixed by unvanishing again.

This is a Spigot/Minecraft 1.8 issue. There's nothing we can do to fix it.

👍 This issue is very annoying as a server owner, and it's gone on for quite some time.

Is there an open bug report on this? @vemacs

Closing in favour of #1764 as they appear to be the same bug.
