While player using /afk with feature AFK tab list modification enabled, using LuckPerms, the command for adding suffix is incorrect. A priority is not specified.

Expected behaviour: Running /lp user meta addsuffix Afk

Actual behaviour: Running /lp user meta addsuffix Afk

The right command is /lp user <user> meta addsuffix <priority> <suffix> but I don't see a reason why you use such a weird way, just to display people as AFK in the tablist(?)

Apologies, another plugin was interfering. This was not luckperms fault. Closed
