@BlakeDeGraw Pretty much gave you all the hints here buddy. Would take me a while to make a tutorial and I have a pizza to prepare.
In short, you have your NPC Blueprint. In Event Graph, you want to create a Transform variable. You want to save the world transform of your actor in that variable. Then you want to run a check (like a timer by fonction name, looping, setting the Time at 1 (second); checking every 1 second is probably enough. Avoid checking every frame, that’s all.) to know if your actor Is Valid. If False, then you can respawn.
This is the easiest quickest way I can explain to a beginner, but it’s definitely not the most elegant. It would take a while to explain the absolute most efficient one, but this should get the job done more than enough.
Hope this helps.
