I know this, which was the reason I once questioned if the paths where we choose PDC would/could possibly gain a limited "snoop" (which does not drag you down like normal snoop does if you use it without foresight) and on the Davis path we saw it in 0.30, with the pics and texts from your wife at his house.2. Yes the physique restriction is intentional. PDC gives extra stats but you lose Snoop.
I stumbled over a save bug, which might be already mentioned by some patrons. If you change your wife´s portrait pic with "summerfun" and later on return to the "standard" portrait everything is okay until you load a save. Once you fire up a save, the portrait progression is scrambled. Your wife´s starting portraits pop up out of sequence often and sometimes stays like this for an extended time. For example, if you load a save from before you go on the weekend hike, her standard portraits show up where her portraits with the bangs should be there.
