This is a regression. Tested in //UE5/Release-5.2 CL26001984
The editor crashes with an assertion after saving a World Partition enabled level with a landscape that contains a PCG Volume.
Expected Results:
The Map is saved with the PCG Volume in it.
Actual Results:
The editor crashes with Assertion.
Assertion failed: LandscapeGuid.IsValid() [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Landscape\Private\Landscape.cpp] [Line: 4780]
