My Ops and I, ( i am the owner, and having same problem). We changed from craftbukkit 164 to spigot instead. Now, they are not shown at scoreboard (TAB) and can only be seen at playerlist (/list).

Which is the problem?

no. i havent changed the vanish settings for months, and i got spigot today.

well, we do have a plugin HIDESTEAM, making us joining vanished, but not preventing us from going unvanished.

What happens when you try to unvanish?

nothing happens when typing /vanish. the /list will show us as listed or hidden, but thats all we can get. We are still invisible.

We can not go visible.

Did you perhaps grant a node that has you join vanished?

We have got it fixed now. Was important to update.
