What can I do to get rid of MapCheck warnings after moving assets to another location made most objects invisible?

I'm having MapCheck warnings and missing meshes/materials after moving several assets to another folder and fixing redirectors. Maybe there are some types of assets or files associated with landscape that I should never move.

I've tried painting information on the landscape and saving it as another scene. Nevertheless, I continue to get these warnings.

landscape painting mode

Same here,
Warnings only on the start, if I check the map from Build > Map Check, so there no warnings.
Have no idea what is, but fixed by resize landscape (with same parameters as it created)
Landscape mode > Resize > Apply
I suggest to try first on the duplicated map
