Seems to be an issue with the landscape material. Trying to move the file causes this error

Can’t save
D:/Repos/MapError/BattleTank/Content/_Levels/Battleground.umap:
Graph is linked to private object(s)
in an external package.
External
Object(s):
LandscapeMaterialInstanceConstant_6
LandscapeMaterialInstanceConstant_8
LandscapeMaterialInstanceConstant_4
LandscapeMaterialInstanceConstant_10
Try to find the chain of references to
that object (may take some time)?

Selecting yes fails to work and then continuing/cancelling causes the map to be corrupted and trying to load the moved file causes the editor to crash.
A workaround is to move the file and then remove and readd the material (Or the other way around) in the landscape’s details before saving.

Edit: Appears to be UE-62150

Oh I see it’s already there (UE-62150), though my post has additional information.

I reviewed it and it is working right now.
