How to save - Actor's current Mesh?

I have a system implemented that:

1 - Spawns an actor with a Random Mesh

2 - Saves game object, with save reference and one local array / save array for game object

3 - Tries to load the data

Problem: The mesh array is empty - i’m wondering if it is because it cannot save meshes.
How can i go around this problem?

Error:

LogUObjectGlobals: Warning: Failed to find object 'Object None.None'

It totally can save references to meshes in the Content Browser. I just tried and it works just fine:

How are you saving and loading? Can you show some screenshots?
