Changing the Max LODLevel on a landscape causes a crash in content examples.
1. Load Content Examples, open Landscapes level
2. Select a landscape
3. Set LOD / Max LODLevel to 0
4. Save level (crash may start here)
5. Exit UE4 editor
6. Start UE4 editor, load Content Examples, open Landscapes level again
Result: Editor crashes when trying to load the landscapes level after changing Max LODLevel
