Memory Leak occurring when making procedural content with the Construction Script

When modifying an object that makes changes using the construction script seems to cause a memory leak. The memory that is used seems to never be freed up.

1. Download, Unzip, and open the attached project.
2. Drag a copy of NewBlueprint into the level
3. Select the NewBlueprint instance and move the EndPoint widget around the area along the X/Y axis
4. Monitor the editor's memory usage.
Result: The memory usage steadily rises while modifying this object and never goes back down
Expected: The memory should only rise as the object count rises but should lower again when the object count lowers or when the instance is deleted
