It's important to note that "Picnic at Asgard" refers to two separate events. On the one hand, Asgard™ is a theme park visited by the Eleventh Doctor and River. Permission was given for this story by Moffat. On the other hand, in a novelisation written by Moffat, Asgard refers an adventure shared by River and the Tenth Doctor amongst the Old Gods. Both happened and both are valid.
