Scene Graph Meshes Lose Material After Exiting Render Distance

Summary

As you can see in the video, meshes start out with the correct material, but after exiting render distance and then re-entering, they render with the default grid material.
In the video, the blue base has the default prefab materials and the other bases have overriden materials, and the bug happens on both instances.
This can be reproduced on a UEFN session and on a private code outside of UEFN.
This was not happening in 40-41 (although a different issue with overriden materials in SG meshes was happening).
