Not sure if this is a bug.
I have BP actor with certain logic as part of its BeginPlay event. It’s a timeline object that scales the actor up. It is used to give the actor a ‘growing’ effect when it gets spawned, since spawning the actor results in its BeginPlay getting called.
If I create a level sequence and spawn an instance of this actor however (by making it a spawnable in the sequence), the actor instance just appears in the level but its BeginPlay does not get called. This means the actor does not play the growing effect.
