Reproduction steps:

1. Create Rabbit Livestock Area
   1. Designate an enclosed space as a livestock area.
   2. Place six male rabbits (one possibly still a baby) of Breed A and one female rabbit of Breed B.
2. Set Up Feeds and Water
   1. Position three feeding trays
      1. One filled to maximum with water
      2. One containing about 150 units of cut grass
      3. One with two bags of animal food (left in the tray).
3. Leave the Area for 2–3 Days
   1. Move away from the livestock area so the rabbits (and area) are presumably running in the background for about 2–3 in-game days.
4. Return to the Livestock Area
   1. Approach your house and notice a drastic drop in frame rate.
   2. Once inside the livestock area, observe a massive number of rabbits spawning and hopping in one spot (60 rabbits per minute).
   3. Opening the Livestock Info Panel causes the game to drop to around 1 FPS, making it nearly unplayable.

I have now his this issue on 42.3.1.  WAVES of Rabbits. In the image below the first wave started near the door to the house near the butchering hook. You can see the next waves comes from an area to the north, past the cars and west of the mobile home.  This just happened while I was working in the fenced in area of the yard. Hopefully, I can recover from this state.
