The patch doesn't appear to help matters. While on the open relationship path, the devs give us the following advice through Kaili:
For an 'honest MC' pursuing Jaye and Mallory on the open path without fooling around with any side girls (even saying NO to the Amanda threesome!), there is ZERO chance to succeed with both of them. If you commit to Jaye after the concert in 1.01, you cannot get the polyamory option.
This is one of many examples of false hope given by the devs that leaves a sour taste in the mouth. It would have been better not to tease the possibility at all if there was never any intention of letting it happen. This is the kind of trust-breaking that kills my interest in future titles from the devs, which is the part of it all that is so heartbreaking as a fan.
