[CoL] All animals aging up/dying

It's happening in my game every time I load the save (not the household). Whichever household is loaded first gets the ripper. If I go to Manage worlds after that and load another household in the same save, their animals are fine. Save included (it's modded, but the same thing happens with the mods removed, with animals in Henford, as well as elsewhere, in any household that has them, if it is loaded first).  Save file

Edit: Regardless of animal aging enabled, or disabled, even chicks get "One..last..pet" on load. It started happening in my game after the last pack update (not the small bug fix).
