Whenever I use /home Farm (my home name is Farm), it sends this line in the server logs and just disconnects my client. Same thing with /gamemode <gamemode>:
lost connection: Internal Exception: java.lang.NullPointerException: Cannot invoke "java.util.List.removeIf(java.util.function.Predicate)" because "this.muted" is null

(just says disconnected on my client log)

does the /gamemode <gamemode> disconnect keep happening if FabricHomes is removed?

Oh, huh it does disconnect me. Must be smth wrong with another mod/config, thanks lol.
