Buggy source:
public boolean exec(IPlayer player){
  if (player.hasPermission(PermissionNames.ADMIN_WEANYWHERE)) {
    String name=player.getName();
    UUID uuid=player.getUniqueId();
    if (!plugin.getPlotMeCoreManager().isPlayerIgnoringWELimit(uuid)) {
      if (serverBridge.getConfig().getBoolean("String_Node_Str")) {
        plugin.getPlotMeCoreManager().addPlayerIgnoringWELimit(uuid);
        serverBridge.getPlotWorldEdit().removeMask(player);
      }
 else {
        plugin.getPlotMeCoreManager().removePlayerIgnoringWELimit(uuid);
        if (plugin.getPlotMeCoreManager().isPlotWorld(player)) {
          serverBridge.getPlotWorldEdit().setMask(player);
        }
      }
      player.sendMessage(C("String_Node_Str"));
      if (isAdvancedLogging()) {
        plugin.getLogger().info(name + "String_Node_Str");
      }
    }
 else {
      if (serverBridge.getConfig().getBoolean("String_Node_Str")) {
        plugin.getPlotMeCoreManager().removePlayerIgnoringWELimit(uuid);
        if (plugin.getPlotMeCoreManager().isPlotWorld(player)) {
          serverBridge.getPlotWorldEdit().setMask(player);
        }
      }
 else {
        plugin.getPlotMeCoreManager().addPlayerIgnoringWELimit(uuid);
        serverBridge.getPlotWorldEdit().removeMask(player);
      }
      player.sendMessage(C("String_Node_Str"));
      if (isAdvancedLogging()) {
        plugin.getLogger().info(name + "String_Node_Str");
      }

  }

  return true;
}

Fixed version (ground truth):
public boolean exec(IPlayer player){
  boolean defaultWEAnywhere=serverBridge.getConfig().getBoolean("String_Node_Str");
  if (player.hasPermission(PermissionNames.ADMIN_WEANYWHERE) && plugin.getServerBridge().getPlotWorldEdit() != null) {
    String name=player.getName();
    UUID uuid=player.getUniqueId();
    if (plugin.getPlotMeCoreManager().isPlayerIgnoringWELimit(player)) {
      if (!defaultWEAnywhere) {
        plugin.getPlotMeCoreManager().removePlayerIgnoringWELimit(uuid);
        if (plugin.getPlotMeCoreManager().isPlotWorld(player)) {
          serverBridge.getPlotWorldEdit().setMask(player);
        }
      }
 else {
        plugin.getPlotMeCoreManager().addPlayerIgnoringWELimit(uuid);
        serverBridge.getPlotWorldEdit().removeMask(player);
      }
      player.sendMessage(C("String_Node_Str"));
      if (isAdvancedLogging()) {
        plugin.getLogger().info(name + "String_Node_Str");
      }
    }
 else {
      if (defaultWEAnywhere) {
        plugin.getPlotMeCoreManager().removePlayerIgnoringWELimit(uuid);
        serverBridge.getPlotWorldEdit().setMask(player);
      }
 else {
        plugin.getPlotMeCoreManager().addPlayerIgnoringWELimit(uuid);
        if (plugin.getPlotMeCoreManager().isPlotWorld(player)) {
          serverBridge.getPlotWorldEdit().removeMask(player);
        }
      }
      player.sendMessage(C("String_Node_Str"));
      if (isAdvancedLogging()) {
        plugin.getLogger().info(name + "String_Node_Str");
      }
