On March 21, some collections have been deleted (id: 188196 and 188139).

Movie related to those collections (eg 35554 and 231176) are not present when I make the call to "http://api.themoviedb.org/3/movie/changes?api_key=KEY&start_date=2015-03-21&end_date=2015-03-22&page=X" ( for all pages and for days to follow).

That is, when a movie is removed from a collection, the event is not captured and raised by API?
