Cant switch paths. Always stuck on mind control.
Idk if this is your problem but I was a bit confused at the start too. You get different MODIFICATIONS offered depending on when&where you meet Mia*. At the start you should get breast expansion if you try to modify her in the kitchen, and mind ctrl if you try to modify her in the living room in the afternoon. If you have trouble finding a branching path try modifying her elsewhere. Please ignore my comment if you tried that already
