Full Moon?, to much light especially with the snow cover, IR never kicked in. You can adjust your IR sensitivity to fix this.

I liked the rubber hammer answer. I'm wondering if he mighta gotten way way below 0F degrees. funny things happen in that realm.

If I had to guess, a little condensation + freezing temps = iced filter mechanism.
