When working in Manage Mode with Landscapes and deleting a component, if you undo the deletion, you can no longer modify or select the component.
I did attempt to rebuild the scenes lighting and geometry to see if that fixed the issue, but that did not help.
Tested Binary Releases
4.8.3- 2634408 - Issue does not occur
4.9.2 - 2707645 - Issue occurs
4.10 Preview 2 - 2733139 - Issue occurs
4.11 - 2734688 - Issue occurs (also cannot see the orange highlight selector while in edit mode)
1. Create new landscape.
2. Delete a few of the components.
3. Ctrl+Z to undo the Deletion
4. Attempt to select the modified landscape components.
Expected: The deleted components are still selectable and editable after deleting and undoing.
Outcome: Can no longer edit the components that had previously been deleted.
