I have three sims I played as young adults and through University. One had a father who got a degree as well.
All three sims got the extra two traits - one from reaching the top of a social group, and one from graduating university.
Once they got back to the main hood, I moved them out of the house they were sharing. One to a new place, the other two I married and moved to a new house.
Now all three of them have lost their extra traits! I'm really puzzled. I know they had all seven when they moved back, but now they are all down to five. The couple I am playing have their degree history. It's clear they graduated and got A's, but no extra traits.
The father who attended uni still has his extras, so it seems like the issue happened on the move.
Anyone else encountered this bug?
