Can someone vet this bug for me? (ShooterGame)

https://answers.unrealengine.com/questions/163683/bug-repro-shootergame-reload-sounds-only-for-last.html

This is really weird, only the last-spawned in player can hear their reload sounds. I haven’t been able to test this outside of the editor, and I’m hoping it’s just a PIE issue, not an actual game issue. I’m on 4.6.1
