Yes, this is it, but the electricity meter needs to be turned off with water and go to the last card. And this map will already be called Raven's House
The last card is a new card added to the game. "The Shepherd's House" But after you spray the electric meter with water, it will already be considered as the Raven's House
A telltale sign that you're in the Raven house is that you don't have Tess, Mannequin, and Sabrina in your trailer. Well, at least it was like that for me.
