Okay doke, Thank you for commenting about this. We have noticed that Poppi is very quirky with her systems. This will get adjusted pretty soon with the next update. With the timing on the night. It's based on your performance. This will be a bit of a spoiler but we are planning on having every night end with Sammy making it to your room, and either fucking you herself, or having one of the other girls doing it whilst she watches.
With this we plan to integrate Sammy to follow a path that you will be able to keep track of if you use the cameras, so players in the know will be able to know how close Sammy is to their office.
(Keep in mind this is not finalized. and we might adjust things as such)
