I'm Polish (sorry for my English)
You closed my topic named: Error NametagEdit Query Failed # 221
The problem disappeared in the console
But the tags are still not working ...

Ah, your github issue was 2 issues. I did not realize. Well, the first issue was fixed, so now about the tags not displaying.

Are you using the GROUP or PLAYER option? Do /nte debug to see if the nametag is being applied.

I do not know exactly what you mean when you use / net debug, tags do not work anymore
@sgtcaze

Test:

1. /nte debug
2. /nte player YOUR_NAME prefix &b

When you join the game, do you see something like this?

Does it apply the nametag or show any output?

As there has been no update in over a month, I will close this issue. If you still experience issues, or if anyone experiences this issue moving forward -- please create a new issue. There is a chance I will not check this old issue.
