Sims 3 Uni: Term never ends! Sims stuck for weeks in college!!

This problem is BEYOND aggravating; if I make my sims go to colllege & choose two terms instead of one, they will complete their final exams on that second Friday, but never get the pop-up about report cards or going home, and it still says they have 2 days & __ hours until class again! So it continues for weeks & weeks with no graduation or completion of degree, and under the career history or grade or whatever panel, it just says A under which degree I'm going for, but it NEVER changes. My sims have went for one term before & successfully graduated, it's just when going for two terms, they never graduate and the term never ends. It just restarts itself for weeks, & I've already made them drop out, then delete them upon doing that because I don't want to waste my time sending them back & wasting the progress I've previously put towards their degree. If anyone else has had this issue or knows how to fix it, please let me know :/
