sounds like you weren't using the camera in any way it wasn't supposed to be used.

how cold did it get outside compared to the normal operating temperatures for the camera?

have you tried troubleshooting it during the day? when the camera is at a normal temperature? I'm fairly certain batteries also work worse at low temps too.

If you're shooting near your cabin and have access to power, best run an extension chord and not using batteries to run the camera (or anything else), consider using a power adapter like this.
