Two little consistency errors I've seen of late:
Chp1 - I've been being pursued by Ivy (vs Lily); my guess is it was tied to who I opted to walk around with when (friend and I) visited them at the wedding they were catering for - I figured this out by doing it twice and picked a different one each time.
During the Burlesque Festival and Ivy led me to the vacant hotel room - during round two with her, I spoke her name with engaged in our fun, but the dialogue showed I called her Lily.
Chp2 - I stayed with Ivy for more (round 2) vs returning to childhood friend. But when I meet with L & I to discuss the Cowboy party, Ivy accuses me of ducking out on her.
Some part of the choice codes didn't transition correctly from Chp1 to Chp2.
But it did grant me a +4 relationship boost with L & I that I would not have had, since standing her up was a -10 (after testing it), that's a big swing.
