Where does this custom inventory data "live" at runtime?

[anonymous_user_741503d3]

void PostEditChangeProperty(struct FPropertyChangedEvent & e) // for single properties

and/or

void PostEditChangeChainProperty(struct FPropertyChangedEvent & e) // for array properties such as arrays of structs

Yep, this is how I handle things too, very neat stuff.

but I ended up settling on the AActor

Where do you ended up ‘storing’ it? Is it attached to your player or just laying somewhere in the world?
