Elias was a weekend DIY warrior with a mystery: a damp spot on his ceiling that didn't match any pipes. Instead of tearing down the drywall, he bought a borescope. He drilled a tiny 1/4-inch hole, snaked the camera in, and saw a family of squirrels had chewed through a vent seal, letting rain drip directly onto a joist.

Clear your Explorer thumbnail cache (see above) or copy the file to a different location.
This is a bug in Windows 10 that also affects other thumbnails – for example transparent PNG images here and here.
