No, it must be on a the first 3 star win only. If you have already done a 3 star win on all level 11s and not gotten a core then you will not get a core at all from the level 11 sim. The grid above just states the possible items to win, not that you are guaranteed winning any particular item. You have just been unlucky, perhaps you will win one with the level 12 sims.
