[PROBABLY MOD RELATED] Job performance not changing

No nothing happens no matter what. It doesn't decrease or increase. Just stays stuck. 

Hello! I also have this issue and have had it for months. I've taken out all of my mods and it still persists. Work performance is fine. This bug only happens with school performance of children and teens unfortunately. I'm glad I'm not the only one with this issue

So I deinstalled and reinstalled the game AND made a new folder. School performance is now working. I haven't checked the interior designer career yet. I don't know what has caused it. I put all my mod back and it is still working so it seems to not be one of them. 

@Captainsimerica A ridiculous question technically but I have to ask...which world is your main household located?

Checked the prior world too. School is working there now too.

@MicelloTale My main household is in Willow Creek. Before that, they were in the new world from Cottage Living and it still wasn't working. I saw that your problem is fixed but I really don't want to have to uninstall and re-install D:

Update: Just uninstalled and reinstalled 44 packs. The issue still persists and my child's performance is still not increasing.

Another update. I watched the performance meter for my child and saw that it was moving/increasing but would move right back to the same spot all day in the light green space of average while he was at school.

FOUND MY ISSUE! I have mc command center installed and for some reason it's been effecting my child and teen school performance

This is also happening to me. School performance is only improving up to "good" and work performance stays completely still at "average". I'm doing a legacy challenge where I need my sims to get promoted and the children to get perfect performance. It's required or I kind of can't progress to the next generation. Yes, I do have mods. If this is a mod problem I would love for someone to tell me what mod it is. If anyone has any kind of solution to this or any updates I would really appreciate a reply. Thanks so much. I will keep looking around to find a solution myself.

Edit: Lol ok so I know I just posted this but I decided to check my mc command center and for some odd reason the career difficulty setting was set to -10 when the default is supposed to be 0. As far as I remember I never changed this setting and I could never think of a reason why I would ever want to. I changed it to 0 just now and I'm going to test my game now to see if this solved the issue. (spoiler alert. It didn't)

MY SOLUTION: I did the 50/50 method and found out that I had an old version of the "Meaningful Stories" mod that was causing all this. I took it out and now it's working just fine. 

I had the same problem of school performance not increasing. it would even drop down or stay the same. But after the 50/50 Method i found out that i had an old version of twisted mexis tool Mod. The old Version also caused lama icons on parenthood chance cards, but with the newer version this is fixed and everything works normal again.
