Mansion in the mist inaccessable

I began completing maps with blue sparkles to find "Draiocht Hengestones" and unlock the Mansion in the mist map. After doing several hengestones the next map to have the blue sparkles was the Mansion itself! I can't unlock the mansion because the next hengestone needed is in the mansion.
