But these plugins doesn't matter, main issue is between NameTagEdit and bungee plugin - BungeeTabListPlus https://www.spigotmc.org/resources/bungeetablistplus.313/

Please explain your issue. How do you trigger it?
Hi, I have weird issue. I'm running multiple servers on my bungee network and almost on all I have NameTagEdit. On Bungee network I have plugins, such as BungeeTabListPlus. The problem is, when I remove BungeeTabListPlus from proxy (due to testing for ex., but it doesn't matter, even if I decide remove it forever, this issue could be solved), and when I have NameTagEdit enabled on my Semi-Vanilla server, then mentioned error below happens. There are multiple teams, I tried remove scoreboard.dat from world and it wasn't solved. Weird is, that it happens only to me... and only on this server. As mentioned, I normally have NameTagEdit on other servers too, and when I try to connect to these servers when BungeeTabListPlus is disabled (or removed), I normally can. The problem is when I try to connect to this server, then error appears. Tried with another players and yes, they can normally join there, just I can't.... and don't know why, when I tried delete also scoreboards.dat.

Contacted also BungeeTabListPlus dev about it and he told me:
I recommend you make sure NameTagEdit is up-to-date. Removing the scoreboard data (scoreboard.dat, somewhere in your world folder) might help - removing it resets all scoreboard data.
But it's up to date and I tried removing it and it doesn't help. So I'm trying to contact you. Can you help me please?

Are there any errors in the console? Please use: https://pastebin.com
