Okay, having finished a run, I'm curious ...
I see in the OP that some kind of change was made, not sure it was to story or just code.
But also, I thought I read (somewhere) implications that Isa's relationship could have been farther along than it reached for me, but that could just be 'cause I gave Alex the full attention she deserved.
So my question is: was there a path progression change that would account for my experience (or lack thereof) with Isa, has her romance never really taken off yet, or should I try a less-faithful path to see more of her content?
