Issues spawning and de-spawning one entity from another.

I wanted a constructed entity (entity A) to spawn another entity (entity B) when construction of A was completed.

To achieve this, I simply added:

construction_ext
on_construction_actions
spawn_entity\ entity_blueprint : Link to Entity B ebps here with a duration of 9999.

So great, it does indeed spawn Entity B when construction is complete.

As a sidenote, I also tried adding spawn_item directly under action_apply_ext \ actions and that works too.

However, the problem is the spawned entity B doesn't seem to attach or be bound to entity A, meaning that if entity A is destroyed B remains.

Under advice I had a look at the retreat point ability and so far as I was able to tell, the ability when toggled on spawns the retreat point and the marker entity but there's no clear indication of de-spawning mechanics inferring that the spawned entity only exists for as long as the ability is active and upon toggling off the perquisite the entity can not exist and thus doesn't.

Yet it seems to work differently when an entity spawns another automatically.

Am I missing something here? Thanks.

What you could try is adding a filter action to the death action of entity A that would target your entity B and destroyed it like that.
