The move was to allow the temporary fences in Animation Courtyard to be moved further into the park so that construction could fully begin on the Toon Studio attractions.

Now, after many months of confusion for first time guests, the park map has finally been updated to show the change, with the trailer filling the gap in Production Courtyard. No other alterations have been made to the map, but it seems likely, according to many sources, that the lack of information about the attractions currently under construction at the park is “set to change soon”…
