Buggy source:
public static CommandSpec getCommand(){
  return CommandSpec.builder().permission("String_Node_Str").executor((source,args) -> {
    if (!(source instanceof Player)) {
      source.sendMessage(Format.error("String_Node_Str"));
      return CommandResult.empty();
    }
    List<ActionableResult> results=Prism.getLastActionResults().get(((Player)source).getUniqueId());
    if (results == null) {
      source.sendMessage(Format.error("String_Node_Str"));
      return CommandResult.empty();
    }
    results=Lists.reverse(results);
    int applied=0;
    int skipped=0;
    for (    ActionableResult result : results) {
      if (result.getTransaction().isPresent()) {
        Object rawOriginal=result.getTransaction().get().getOriginal();
        Object rawFinal=result.getTransaction().get().getFinal();
        if (rawOriginal instanceof BlockSnapshot) {
          if (((BlockSnapshot)rawOriginal).restore(true,BlockChangeFlag.NONE)) {
            applied++;
          }
 else {

        }
        if (rawFinal instanceof Entity) {
          Entity entity=(Entity)rawFinal;

            entity.remove();

Fixed version (ground truth):

    }
    List<ActionableResult> results=Prism.getLastActionResults().get(((Player)source).getUniqueId());
    if (results == null || results.isEmpty()) {
      source.sendMessage(Format.error("String_Node_Str"));
      return CommandResult.empty();
    }
    results=Lists.reverse(results);
    int applied=0;
    int skipped=0;
    for (    ActionableResult result : results) {
      if (result.getTransaction().isPresent()) {
        Object rawOriginal=result.getTransaction().get().getOriginal();

        if (rawOriginal instanceof BlockSnapshot) {
          if (((BlockSnapshot)rawOriginal).restore(true,BlockChangeFlag.NONE)) {
            applied++;
