Thanks for the bug-reports; I'll have a look at it.
Mia's original first movie had a dark and a light side ending for them; the dark side was trimmed as the game went along (I didn't like how it felt, to be honest, and it would break all dialog afterwards). That's why the games makes a big deal of the ID in the beginning, since the dark path would involve finding her 'real' ID in the shoulder-bag (she'd leave it in the office once the photoshoot started) then use the fake ID to blackmail her into sex.
I like the ending better now :)
I'll check out the other issues mentioned; thanks!
