Yep, Medici fights are special because they have no % placement rewards, only a flat top 100 leaderboard.
On a side note, please double-check the category under which you create a thread next time. You've posted this under 'feedback & suggestions' when it probably would've been more suited to go in 'known bugs & issues'. If you had, it would also have given you the ability to tag the thread with a more specific bug label to say whether it was to do with gameplay or a 'hard' crash or a visual error etc. It's not too much of a problem but it helps to keep the place organised.
