already mapped the pixels before. those hot pixels don't appear "cold"

The general idea of Pixel Mapping is to ask the camera to look for dead pixel and map them out for future usage (to mark the location of those dead one).

Hot pixel is generally caused by heating up of the sensor. It is not a dead pixel. Most of the time hot pixel will return normal after cooling down. Therefore, Pixel Mapping won't deal with them.

If hot pixels appearing under non long exposure shots, or reappearing on same location, that could be a dead pixel instead and it would need Pixel Mapping to deal with them.

Therefore to your question, would you see similar hot pixel under a 1/60" dark frame shot?
