Hey Rama,

I just came about the need of versioning the save files. Did you consider that in your work yet? As a file loads the actors directly, every versioning needs to happen inside of the actor class itself.
One versioning thing I just came about is renaming of parameters (member variables). As your save system uses UPROPERTY to save/load the members by name, loading is broken when renaming happens. Would be nice to have something like:

Before loading: Remap the actor class. Like:

 RamaSaveVersioning_RemapClass(FString oldClassName, FString newClassName); 

Would be nice to use string for the new/old class name. Using UClass would need the old class still to exist. FString would make it possible to delete the unused stuff.

During actor load within RamaSave_PreLoad:

 RamaSaveVersioning_RenameProperty(UClass class, FString oldPropertyName, FString newPropertyName); 

Cheers.

These are excellent points, even as a starting point it would be great if:

1. I added user-chosen global version number in plugin settings
2. I gave you the opportunity to rename a property on load that you know you changed the name of, so that you can redirect my system to the new name.
3. Probably renaming a class can be done the same way, where I give you chance to change the class name before trying to load it.

I will work on this soon
