I don't believe any are affecting but I have Featherboard which is a major plugin that interferes with NameTagEdit scoreboard. So I think the issue is that it is manipulating the NameTagEdit TAB displayslot board.
But here
Plugins (20): BlockVersion, ChatManager, Citizens, CommandNPC, Essentials, EssentialsSpawn, FastAsyncWorldEdit, FeatherBoard, HiveJumpPads, HolographicDisplays, IPWhitelist, LuckPerms, MVdWPlaceholderAPI, NametagEdit, NoVoidFall, PlugMan, ProtocolSupport, Vault, WorldEdit, WorldGuard

Please explain your issue. How do you trigger it?

I used NameTagEdit before, and I know how to setup the plugin groups and configuration correctly.
But the issue is, when I used to change the group of a user to a complete different inheritance, the nametag used to update as per the permission set in groups.yml and in LuckPerms, automatically, without needing to set any refresh interval. But now the tag does not update at all, I don't know if I'm doing something wrong, the only difference is that this time we use the Featherboard plugin.
I have disableTabList now set to false in config.yml and still no result, and I don't want to setup a refresh interval since I made a plugin that uses the API to get the name tag and set it in the player's chat, and a refresh interval will make the chat sometimes glitchy and throw up some NullPointerExceptions in console. (Which I believe the issue is when the name tag refreshes and a player sends a chat message at the same time, the nametag will flicker in tab, hence the plugin fails to get the name tag and throws a NPE)

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

The only error I had with this plugin so far is the NPE when my chat plugin fails to get the name tag of a player.

The error appears to be coming from:

com.sasoftwares.chatmanager.ChatRankListener.onPlayerChat(ChatRankListener.java:25) ~[?:?]

Which is the ChatManager.

Could you try removing this plugin and see if everything is working as usual? If not, please post your configurations.
