It happens to me too. No mods/cc in my game. Started a fresh save, and play with an existing family in Mt. Komorebi.
Not only they don't change into their schooluniform (when wearing ANY type of clothing, so not only pj's), but the whole family (in fact all the Sims in all the worlds) never change to/from hot or cold weather outfits going outside or back inside. This problem already exists since Seasons.
Maybe the not changing to schooluniforms belongs to the same problem?
The pattern I am seeing so far is that when I play with the Akiyama, which only has kids, they change into uniform. The Nishidake only has a teen and she also changes. However, when I play the Ito family, none of the kids change. Maybe it's the teen and kid combo that breaks it or it's something with the lot?
I am also experiencing this. I have mods, but doubt that my use of them is causing the issue since this is apparently happening with or without mods. I'm currently playing a teen that lives on his own that I put into the Snowy Retreats world (sorry, just got the game, can't recall the name). I imported him basically from another save and placed him into the new save file. Not sure if that affected it or not, but I can try and do another save file without mods and create a family from scratch to see if the problem is from me importing the sim or not.
Steps i did when trying to test this bug to help out the devs.
Moving a family into Mt. Komorebi - Applies uniforms to sims as it should
Used the same family but moved them into the following worlds first ( Newcrest, Sulani, San Myshuno, Not tested the rest) then moved them to Mt Komorebi. It did the bug you decribed.
If anyone else is willing to try this test i did on a clean save file WITHOUT mods and CC im sure they may/will get the same results. It is my theory that when moving sims from one world to Mt Komorebi it does not override the education system so classes teen and children as if they still lived in another world and does not apply the school uniform.
I had a similar issue. Moved a family from Bindleton Bay to Mt Komorebi when the pack came out, and the child won't change. Now I've aged my toddler up, she changes into her uniform fine but the other child still doesn't!
I've also this problem, haven't found any answer on what to do. She was wearing school uniform during her first school day, but she has been wearing her normal clothes the rest of the days np matter what season.
to be honest.... my children/teenager never did change their clothes when going to school... it bothers me since forever...
I was also looking for a mod to do that
are children and teeanger supposed to change into "work outfits" (in this case some kind of uniform) ?! Is this, how the game should work? Or is this just a wish from us, that children/teenage should change their clothes?!
Hey, having the same problem here. I actually only just noticed because I had completely forgot they were supposed to wear uniforms in Mt. Komorebi. But yeah, my child sims (will see if it's different when they're teens) aren't changing in to their school uniforms when going to school either. Very annoying.
