Skilled sims are problematic?(ones saved in gallery)

long ago (january 2023) i started to play sims 4.Before i played not sure which sims somewhere 2006.

to the 2024 i had almost 10  generations and it was a mess. Then somewhere middle 2024 i screwed up my save with [Edit - CM].  then i started again amd made a mess with 8 sims gamily and started again from zero. then i  deleted original sims and tried to make similar to originals( in pic) and then i made my sims pretty skilled and again didnt liked how family went lol. and since i play with sims who are skilled i keep catch weitd bugs even if game itself isnt laggy or so.

any opinions on if i should make very news ones or current ones are fine?those on pic are best i made lol
