NPC Sims are unable to be convinced to do my Sims' homework or to do homework with my Sim.

It happened in a new save and I discovered a last exception file generates when this occurs.  In this save, my Sim was not enrolled in University and no Sims I have played were ever enrolled.  The Sim Lilith Pleasant came over and left her homework.

@canelacaliente Confirmed - I also had "lost homework" on the table in every dorm I have played so far.
