Lets say i have a Texture asset (just as an example it will be the texture, it can be any UObject)
References are:
Texture → Material → Static mesh → Actor → World.
Lets say i changed the first asset, and now need to perform the LOAD operation again in runtime, without breaking references.
(Mark as garbage → Garbage call → Load) ||| ← isnt a solution, it crashes the game (which is obvious since our refs become invalid).
Everything here is happening in RUNTIME
