[CoL] Animals die of old age although aging is set to off

Unfortunately I have to re-report this old bug. Several of my bunnies died this morning. Animal aging has never been turned on in any of my saves. 

This bug was listed as fixed in a recent patch (https://forums.ea.com/idea/the-sims-4-bug-reports-en/col-all-animals-aging-updying/11853294). Unfortunately it doesn't seem very fixed from where I'm sitting with sad sims on a bunny graveyard. 

I have the same problems as described in the old thread that's marked as fixed: animals die off when I return to a lot after a while being on other lots. 

Closed the game without saving after all my critters died and turned off mods and cleared cache and localthumbs, and tried loading into a mod-free save, only to see the bunnies there also dying basically immediately upon loading into the lot they were on.

Latest game version/patch.

Did not try other farm animals, because I mostly just place the bunny stump on my lots for cute bunnies hopping around my gardens and parks. Well, several of my sims are now very sad about the death of their cute garden bunnies. 🙁 I am also very sad about my cute bunnies dying; I thought this was fixed. 😭
