Hard to me to understand how someone could lose an animal to rot. We have to pack out our elk and at least this year, 2 out of 3 were in very warm weather. Getting to the animal skinning, quartering them is important and putting the quarters in game bags keeps the flys off them. We had temps in the 30's at night and 60's during the day at the cabin but the quarters in bags were hung in the shade and in the ever present wind stayed cool. Moose are a bit bigger but the same thing works for them just like elk, caribou, deer and turkey all of which I have experience with. I have hunted for over 45 years and never lost an animal due to spoilage other than one that couldn't be recovered until the next day in warm weather.
