4. Open the “Testgrounds/Graphs/RecentGraphs/poiSet_nuclearPowerPlantReactor01” Graph Model
5. Press the “Load” button in the “GraphWindow” window
6. Select the “poiSet_nuclearPowerPlantReactor01” Graph Model
7. Repeat steps 5-6 multiple times
8. Capture a new snapshot
9. Compare memory usage results between snapshots

Expected result: None or slight difference in memory usage
Actual result: High memory usage
