@export var x: Array[String]
```

### Minimal reproduction project

n/a
nd.owner = 0;
	} else {
		nd.owner = -1;
	}
	MissingNode *missing_node = Object::cast_to<MissingNode>(p_node);
	
	
	if (states_stack.is_empty() && !is_editable_instance) {
		
		if (missing_node != nullptr) {
			
			nd.type = _nm_get_string(missing_node->get_original_class(), name_map);
		} else {
			nd.type = _nm_get_string(p_node->get_class(), name_map);
		}
	} else {
		
		
		nd.type = TYPE_INSTANTIATED;
	}
	
	
	
	
	
	bool save_node = nd.properties.size() || nd.groups.size(); 
	save_node = save_node || p_node == p_owner; 
	save_node = save_node || (p_node->get_owner() == p_owner && instantiated_by_owner); 
	int idx = nodes.size();
