Sims stretch while doing interactions (Reason Unknown)

Hi!! so I come and go in the Sims, meaning I play for a while, and then I don't, like most of you. I have been experiencing stretchy infants again, now I haven't seen that since Growing Together came out, or maybe even the infant update. I did have mods on, but since it was happening, I turned them off, and it just seemed like there were even more glitches, not just the stretchy infants, for example, adult sims picking up infants and putting them down, actions canceling, bottles and dippers being put on the ground and not in the trash can. My Sims are not even moving to pick up the infant. I was also having an issue with aging up the infant; my sim would not bring her to the cake, so I just cheated to a toddler in CAS. I was playing with the sim Alex Moyer, and I heard she is kinda immortal, so I turned her into an infant. I wasn't sure if she was the problem because she is immortal?? IDK, but I beg of you, fix infants. I know that these problems have been ongoing. Also, please fix the doctor career in Get to Work, YOU CAN NOT TELL WHAT SICKNESSES SIMS HAVE. I came back to play this, and holy heck it's sooooooo hard. I mean, I like it hard, but not that hard!!!

I have a big Family and I witnessed too many times that my babies, which are crawling around are sometimes standing up, having long arms and legs. (And sometimes they have animal paws? Even tho I don't have an animal pack installed.)

I only play with the Seasons Pack, Laundry Day Stuff and Housecleaning Set.

do they have any specific interactions in their queue when they do that ?

crinrict​ What I see is, that they just look around, shortly before they crawl somewhere. I'll look further into it, if it happens again

I found out (In my Save), that the stretching mostly happens if the babies are ''cooing'' at someone

(Edit) - Happened, directly as the task/automated task was taking place.

I also get this too. What happens for me is that when NPC Toddlers arrived at the Playground for the first time they stretch as soon as they arrive. It happened when I was testing the new lot in a completely clean unmodded folder in a new save while testing for my bugs. I was trying to find hidden features in the playground lot before I go back to modded. I did do a clean folder for sims 4 by taking the old one out and repair my game to see if any issues pop up. This issue popped up for me in a modded save but after I did all this and moved the entire sims 4 folder to the hard drive and repaired the game and it still popped up. Hope this helps and no none of my sims inventories didn't go missing in my test. I did test that too. It's unknown why this happens to me so I posted it here since it's unknown. I do want to add is that when they show up again. They don't stretch again. This is to me unknown what is going on. I will create a thread to see if anyone has the issue of this when toddlers arrive to lots stretching since this could be own thread worthy. Edit= I created my own here about this. https://forums.ea.com/idea/the-sims-4-bug-reports-en/npc-toddlers-stretch-when-visiting-playground-lots-for-the-first-time-/12623350
