Just had my only set of power armour, nicely modded up, and set in the PA station, with no fusion core, disappear on me.

Power armour, and doors, and beds, need 'player only' locks put on them.

Why make them treated differently by the game if they get stolen and used by NPC's?

Beth development motto: Why do it right, when you can do it half right!

The Vault-Tec of game development....

(Narky comments included as that might get some development interest...yeh, right, dream on...)

No fusion core in it makes me think an area respawn may have caught it.
Watched that happen the other day trying to bring home one suit I had found in a lake.

Reloaded and parked the a suit near Covenant while bringing the extra back.
This time the suit persisted so no reload was needed.
