The main issue with your viewpoint of people already having played it is this is an unfinished game, it doesn't really matter what people played. While a game is unfinished, it is subject to possible change. It is the entire point of an unfinished game to change as needed and to be polished, not to stay stagnant and the same as when the project started.
Sorry but it very much DOES matter....
Ask the folks from Dual Family who had an entire stretch of time and scenes ripped from the game in the last release!
What he has completed IS COMPLETED!
If he didn't think through how to get where he needs to go then that's his problem.
I don't want to DejaVu my way to the path he should have thought about when he started the path...
And I certainly don't want chunks of my memory regarding these people ripped from my skull, just because it is easier to pretend it never happened and removed it from the game...
Then everyone on Lisa GF path is caught in a no mans land until they get with Olivia...
Sorry this isn't a movie of the week that you can change each week because you didn't like the way the story was going...
I gave him two fine ways of bridging the gap and it only takes about three or four renders and a bit of dialogue!
