We found that in a certain use case where we get duplicate names in the UserCollection.
Our site is currently in a Facebook IFrame and only when a user is logged in to facebook they are listed in the UserCollection twice. This looks like a local issue as in the Room Console does not display the user twice. I need to check again to see if other users in the room see the same thing. My first tests show that its not the case and the number of users are displayed corectly.
It looks like LCCS is listing the person twce in the user collection.
Myabe we should use the AS3 API for facebook even though the site currently lives there?
