After successfuly having sex with Latisha and finishing the story with her (the equipment renting), I am cleaning the Studio again on the 2nd day (The 5th. section of the story) but Samantha is not there. I have tryed playing the previous missions again, but it does not fix the problem.
I followed the guide to make sure I did everything right. Can someone help?

Greetings
Ank

Well, you could either restart the story, or we could assume that the save file bugged out (as it sometimes does), in which case I can give you a replacement save.
