How do I respawn enemies?

Hello! I'm a new poster so let me know if I'm missing amy etiquette.

Basically I've been having this issue where these invisible sprites spawn are supposed to only spawn an enemy when the enemy it's originally spawned has been destroyed. However no matter what I try, either the spawner spawns too many or doesn't respawn the enemy and I'm not sure why.

Basically I need to find a way to link a spawner and its enemy untill death do them part.

Here is a demo

dropbox.com/s/mafcfpy62uavkl3/Spawners.c3p

I've done a bunch of testing and reworking and I unfortunately can't recreate this solution. I think the issue is that I'm using a "spawn by name" to create one enemy from a family of several different types of enemies which is preventing me from using the "pick instance by UID" method of checking if there is an enemy still existing.

It should still work with "Create by name". Add a sub-event and use "Pick last created EnemyFamily". Then set Spawner.EnemyUID to EnemyFamily.UID

Thank you so much! This new system works like a charm!
