Changing the name of a newly-created folder that contains a few copies of the same map causes a crash in the Landscape Mountains project.
This crash did not occur in a clean First Person project when following the same repro steps.
1. Open the Landscape Mountains project
2. Go to File->Save As and create a new folder under the Content folder
3. Save the map to the new folder
4. Save the map again with a different name to the same folder as step 3.
5. Repeat step 4
5. Go to the content browser and attempt to rename the folder
Result: Editor crashes after hitting enter to accept the changes to the name of the folder.
