Ancient Multiplayer game Quest stuck on Pt2

I used a credit on the Shattered Dreams mystery box and got the Ancient Multiplayer game which also gives Prince Gautama and a Quest. I am stuck on Quest Pt 2 where Prince Gautama, Nelson, Jimbo and Kearney are made to race emus. Quest dialog box shows Quest as “done” but does not release the characters to progress to the next part. I have tried removing the Ancient Multiplayer Game and reloading game but it doesn’t solve the issue. Any help would be very much appreciated.
