update

Great news! I have finally pinpointed what exactly was causing the Get to Know issue where on completion of the interaction, sims would reset and sometimes cause an LE.
I have been playing, using the interaction in various situations with different sims across different saves and have not encountered any resetting or LEs, and neither has my tester.  Sims are now correctly learning traits again.   

I have also fixed titles not staying on travel and loading, and have changed/added code to make sure this shouldn't happen again in the future with updates.   

I'm just fixing more stuff around my classes and homework, but should release a patch within the next few days.
