A Custom Entity with more than one Custom Hitbox. The Custom Hitboxes do not Rotate the same with the entity, instead it stays the same place.
For example, a custom hitbox will be on the north part of an entity but will not Rotate with the entity's north part, the custom hitbox will remain the same north of the world.
For issues with addon functionality we need you to attach a sample pack that can be used to demonstrate the problem.
