Description

While Niagara Fluids Plugin is active it creates a memory reference of any saved level regardless of being actually used. Simply enabling the plugin shows a memory reference while deleting the level. The reference is not visible in the Reference Viewer.

Steps to Reproduce

1. Start Editor
2. Enable the NiagaraFluids plugin
3. Restart Editor
4. Create an empty map and save it
5. Create another empty map (to unload the saved map)
6. Delete the saved map
7. Observe the 1 memory reference in the "Delete Assets" dialog
