Heyo,
As I've been struggling to find any good resources to learn saving/loading in Unreal Engine, I've decided to make my own resource available for others.
I've made part 1 out of 2 available on Medium, and hopefully this can help someone else struggling with a save/load system.
The article is available here: https://medium.com/@chrhaase_71293/an-unreal-engine-saving-loading-system-part-1-of-2-62244e55e4b2
