Material not found after packaging.

Whenever I try to use the Landscape and package the level I get the following error and the game crashes.
Yes, the material exists and yes it is in the proper directory.
The landscape works fine in the editor.
There is only an issue after it is packaged.
I am using UE 4.23.

Has anyone seen this error before?

It seems that UE 4.24 has fixed this issue. I installed it and the issue no longer seems to exist.
