Okay, that seems HIGH. As was mentioned in the second link I provided:
#26,098 which is reply to a person with exactly the same percentage as you:
#26,097 - it appears you might have done some things too early and others too late. Did you go to the ComicCon before you did the club? If so, go back to a save before the ComicCon and do the club first. Did you do the Mary Cosplay task before trying to sell the jar? It shouldn't matter, but something could have bugged out by doing that.
You've done something before selling the jar that seems to have bugged out Sara appearance. Check the list of tasks in my walkthrough thread and let us know and then go back to a sufficient save to try again.
