Why does "Get Child Component" return a different result in standalone play?

As pictured below, this actor blueprint’s ‘Get Child Component’-node’s other actor child index “1” (boy, say that ten times in a row) returns the desired child component in viewport play (my MyCharacter’s skeletal mesh) but a different one in standalone play (MyCharacter’s camera boom), whereas index “0” gives me the correct result in standalone (and the wrong one in the editor). Does my setup not communicate concisely?

Thanks for your attention :slight_smile:
