Found out my 50 year old house has zero insulation behind one wall

Was patching some drywall in the guest bedroom last week and decided to peek behind the baseboard. Stuck my phone in with the flashlight on and realized the whole exterior wall is just studs and siding, no insulation at all. Checked the attic and saw the fiberglass batts stop at that section too. Looked up the house history on the county assessor site and it turns out the previous owner added that room as a sun porch in the 70s and never insulated it. No wonder that room is freezing in winter and an oven in summer. Has anyone else found a random uninsulated wall in their old house?

My buddy found the same thing in a 60s house, was basically living in a tent year round lol.

@emery_hall bet his tent setup had better insulation than those walls.
