[CoL] All animals aging up/dying

I think there’s something wrong with the way animal aging in an unplayed household is handled, whether animal aging is on or off - though I agree that the fact it happens even with aging off makes what would just be a nuisance much worse. I play with animal aging on, and generally trade my chickens for meat when they reach the point you get the warning they’ll die soon. By hatching any hatchable eggs in the coop when they’re laid (which was a lot easier pre the hatchable egg bug) and trading older chickens for meat as they reach old age, I can give my household a steady supply of eggs and white meat.

However - I have a mod free save for bug testing. Because it’s for bug testing, I have a variety of households I switch between irregularly depending on what I’m testing. Last night I switched over to a farming household I hadn’t used  in a while. About a day into playing the household, Grim arrived for multiple chickens, including one of the chicks, for them to die of “old age” (including the chick) despite not receiving a warning notice. Immediately after, a wild rabbit that my sim had befriended previously dug into the ground and disappeared, with a notice appearing that he too had died of old age and my sim receiving a mourning moodlet.

I noticed then that my remaining adult chickens showed “one pet left” as their age, so tried to trade them in - but none of the chickens or chicks from previous gameplay were available in the trade menu, only the chick I had just bought. The next time my sim traveled, when I returned to the lot the chicks aged up. A few minutes later, they too died of old age. Each time I traveled, more died on return until all animals from the previous time I played the household had died.

 I think animal aging either shouldn’t happen in unplayed households, even with aging on, or it should at least be reflected properly when you return - chicks should not still be chicks if they’re about to die of old age, animals shouldn’t get stuck so you can’t trade them but they also don’t die until travel, and you should get the notifications when you load the household that they’re old. Better yet, if they should have died while unplayed, instead of making you start off your play in that household with a mass reaping, just let them be already gone - load in with a “while you were away, [animal] died of old age” notice and skip the sad moodlets. Maybe even put meat or ingredients in my inventory, or at least simoleons, as compensation for the loss.

(and of course if animal aging is off for the save, none of this should happen because they shouldn’t age at all)
