Foreword: this change could only be reasonably implemented alongside server reset.
Many animals give two hides because maximum size of hide is 2x2. What if maximum size of hide and drying frames was changed to 3x3? Bear/moose/cattle could yield single 3x3 hide instead of 2 2x2 which would make more sense. Also could give more leeway in balancing hides of other animals. Squirrel could give 1x1, Rabbit 1x2 and fox 1x3 hide for example.
