Fix: Unreal Blueprint Spawn Actor Deferred Init Properties Not Set

Spawn a configurable item; set its properties; expect BeginPlay. BeginPlay never fires.

Call FinishSpawning

actor = BeginDeferredActorSpawnFromClass(...);
actor.SetConfig(config);
FinishSpawningActor(actor, transform);

FinishSpawning triggers BeginPlay. Deferred without finish = limbo.

Or use SpawnActor

Skip deferred entirely. Set properties via construction script. Simpler for simple cases.

Audit deferred spawn helpers

Wrap deferred spawn + finish in helpers. Forgetting FinishSpawning becomes impossible.

“Deferred spawn is two operations. Skipping one is a bug.”

Document the deferred pattern in your spawning guide. New contributors will discover it the hard way without docs.
