all players kicked until server restart

^this was the first occurrence of the error, then after that it happens for every new login until a server restart
using paperspigot 1055, waterfall 101
this only started happening after giving all players a nametag that join the server, to make use of the anti-pushing feature for all players
also this usually happens when a different server restarts and all the players from that server are sent to the hub
like if my skyblock server restarts, all the players get send to the hub server, the error occurs on hub, and hub will need to be restarted to fix it
@sgtcaze still happening with those commits
here is the first occurrence of the issue again, after this it happens for ever new player until I give my hub server a restart
again it happened a few moments after a server restart, so a bunch of players from a minigame that was shut down had just transferred to the hub

with priority all set to 0 for my hub server
Apologies you are still experiencing this. I've been testing, and have tried to reproduce this, but am falling a bit short. Do to use a plugin that modifies the scoreboard on your hub?
I have a few more ideas to test out, and given this is a sudden problem (which I definitely believe is related to SortPriority) it is strange then, that given the feature is disabled, it is still presenting issues.
Only thing I can think of could be essentials nicknames (they are changed on the tab list), I am not even sure if that is a scoreboard though. I had a plugin that set essentials nicks on login, I added a delay to that plugin instead of doing it immediately, maybe that will fix it.
it is hard to re-produce for me too, because its been ten days between changing the sort priority and it happening again
Also, if you're using BungeeCord. Make sure your connection-throttle is 4000 in the BungeeCord config, and in the bukkit.yml change the connection_throttle to -1.
This can cause a lot of issues with players upon join if this is not setup correctly.

and players.yml is whatever the default is
I strongly suspect the issue is here: https://github.com/sgtcaze/NametagEdit/blob/master/src/main/java/com/nametagedit/plugin/storage/flatfile/FlatFileConfig.java#L79
as it is being run async from the task created in the join event
I'll take a look tonight and try to get something out ASAP. Async packets = possible no-no.
