The Mirror Mirror Room in the Clubhouse you speak of, was appearing on my primary account but failed to appear on my secondary account ... for days.
I kept thinking... what is different between these accounts.... then it hit me
Try this; it worked for me.
To enable the Mirror Mirror Clubhouse Room check the "Check Box" on the My Options Tab in your book of pets by:
1. Click on "Click here to see all your pets", it's the little "blue pet and plus sign" icon just to the right of your pets portrait on the left of the dock.
2. Click on the My Options Tab
3. Make sure that the "Check Box" for Limit certain third-party advertisements is unchecked.
Now I wonder if this too would have unlocked the Lorax's Adventure Park Quests.
With so many things being a challenge to make work lately and no response from my inquiries to Ganz, it is nice to resolve one.
As for the mirror and Nafaira I haven't seen either of them yet.
