I received an email today regarding this topic, here was the reply below.
I will start taking photos and see if I can find the last hidden mickey, while he didn't say it has been moved that's pretty much the only thing I can assume because he confirmed the quest still exists.
Hi there,We have checked our records and the quest you mention is still in the game.
>With the new changes that you have implemented (love them by the way) the Discovery Island has gone missing. Promotion ending or what not but I was wondering if you moved the hidden mickey that was in that area somewhere else and if it's still possible to complete the hidden mickey 2 quest. As the the golden set coupons have expired I can understand not being able to turn it in but will you be opening another hidden mickey quest? While you don't have to give me that information I do want to know if the hidden mickey has been moved or no longer available.Thank you kindly and I hope you have a magical day. VMK Name: Summer
