Bugs and issues in The Sims Medieval Pirates and Nobles.

does any one know if the best in show ambition is bugged?
I played it and got all of my knowledge health security and culture as high as they could go
but the game auto completed and set my achievement at gold instead of platinum
I usually have to click the little trophy to make the game finish the ambition early

does any one know why this happened or how to fix it
I also have the origin version
