Buggy source:

Fixed version (ground truth):

  if (PermissionManager.hasPermission(sender,Permission.COMMAND_GLOBAL)) {
    if (BungeecordModuleManager.GLOBAL_CHAT_MODULE.getModuleSection().getBoolean("String_Node_Str")) {
      sender.sendMessage(Message.GLOBAL_IS_DEFAULT.get());
      return;
    }
    if (BungeecordModuleManager.GLOBAL_CHAT_MODULE.getModuleSection().getBoolean("String_Node_Str") && (sender instanceof ProxiedPlayer)) {
      BungeeChatAccount account=BungeecordAccountManager.getAccount(sender).get();
      if (!BungeecordModuleManager.GLOBAL_CHAT_MODULE.getModuleSection().getStringList("String_Node_Str").contains(account.getServerName())) {
        sender.sendMessage(Message.NOT_IN_GLOBAL_SERVER.get());
        return;
      }
    }
    if (args.length < 1) {
      if (!(sender instanceof ProxiedPlayer)) {
        sender.sendMessage(Message.NOT_A_PLAYER.get());
