[NEEDS INPUT] [DU] NPCs Lose Homework If the Sim is a playable Sim, have you tried putting homework back in the Sim's inventory? I was having this issue with Lilith Goth. I went into manage worlds and added homework back to her inventory. I then called her over again and I was able to complete the interaction. If the Sim you are trying to convince does not have homework in their inventory, the option will not work.
[NEEDS INPUT] [DU] Option to Convince Sim to Complete Already Completed Homework - The option to ask a Sim to complete a homework assignment that has been completed or the term is over is still present. Is the term over for the class? Has the homework assignment already been completed? If the homework has already been completed for the term or the class is over, you might get that animation.
[NEEDS INPUT] [DU] Dormmates No Longer Behave As Students After Week One or [DU] NPC's Not Enrolled Don't Move Out of Dorms- The convince to do homework does not work on Sims not enrolled in University.
[OPEN] [DU] Rotational gameplay is impossible for University - It could be related to this issue if the roommates are other families you played. They could be unrolled. Check to verify the other families you played are still enrolled in university if you have other families.
[DU] Can Convince Non University Sims to Do Homework - It can be related to this. Sims that are not enrolled in university generally don't have homework and are not able to complete the request. It should give a no interaction but if the Sim was enrolled in university before, it gives a positive interaction that doesn't complete.
well, none of this, i try on roommate, also in the 1st week, they take notebook, but not go to any desk, they simply put the notebook back to their inventory
yes , both
Does the sim you're trying to convince need to be enrolled in the same course for it to work? The few times I tried this, it didn't work
