It's probably not your Sim. There's a bug report that Batuu missions sometimes just won't complete. https://answers.ea.com/t5/Bug-Reports/NEEDS-SAVES-JTB-Missions-don-t-get-credited/m-p/10381143#M183739
@whubble1817 Hi! Sorry you had trouble with that bug. Your sim has such an interesting story! To answer your question, you can take your sim to CAS (or go to manage worlds and then go to manage households to edit) then save the household to your library. Whenever you save a sim, they will retain all traits, career progression, aspiration progression, skills, degrees, and money. This does not include any story progression, like completing the SV story. (I haven't played with JTB much so I don't know if faction progression is retained but I doubt that.) The sims will not retain any relationships or inventory items. I do find it helpful when I want to start a new game but don't want to completely start from square one, like you said. I usually add a note to the description to help me know what they have when I save them; example "This sim has many traits, many level 10 skills, X amount of money and so-and-so degree." Note that if you have multiple sims in a household, they will all be saved with the progress I mentioned above. If you decide to start a new game and remove any sims from the household, the money goes back to the standard $20,000 but they will still have the other progress. Hope this helps!
