Launched myself off a cliff with the ATV and died, on reload the ATV duped and triggered the debug build's dupe detection: https://files.catbox.moe/quvzm1.sav
How bad would it be to continue on this save, by the way? I had just finished cleaning the base and migrating my things out of the mail box, but here's a few events that target the ATV and that sounds like trouble.
...On the other hand, I'm curious what would happen when there's multiple ATVs at play.
