Adding a lot of components to an actor can cause the editor to hang

If the user adds around 400 components to an actor the editor will freeze up and quick responding.

1. Open Editor
2. Create an Actor blueprint
3. Add a static mesh component
4. Copy and paste static mesh component a few times
5. Select all static mesh components and copy paste those
6. Repeat the above until the editor stops responding

Expected: The Editor would not hang
Result: The Editor hangs
