A splash screen popped up 15 hours after I won the Dungeon Dragon. The splash screen was followed by a new Baron's Tent Goal pop-up, showing a new reward.
Then came the Thank you screen and the Capulet Warrior reward notice, but once these were closed, the new goal disappeared. Don't know if it was a new bug brought on by the Capulet Warrior notice or that S8 just decided not to have any goals for this round of the Baron's Tent.
Unfortunately, I didn't capture the screens as I was viewing them at the traffic lights
