You sure about that, I have gotten the full sprite on my end.
The sprites have a loop cycle, where when you re-enter the room, it'll load the next "event", hence a new sprite.
The best example are the maids on the 1rst floor, that cycle their behavior between 3 different interactions that change everytime you enter the room.
With the rescued maid for example, she'll follow this patern :
- swipping the hallway
-taking a bath
-brewing tea
