Is she constantly roaming or is she sleeping out in the open? My guess if your husbandry is perfect then she's probably just a little unique. Occasionally I'll observe mine 'sleeping' outside their hides, if nothing in the viv hasn't changed I'll usually leave them to it. Just keep an eye on everything and as long as everything's good health wise then I'd let her do what she wants

Different snake altogether but the only time my carpet will use a hide is if he's going into shed. Granted they are semiarboreal, but he'll spend most his time up on his shelf or pole.
