Allow MSQ Fast Track To Latest Expansion

[Niwashi]

I also think that it would make more sense to include a story jump potion if it was introduced with an expansion set as part of its cost rather than selling it separately as for the most part only people buying an expansion would need it.

I don't think it should ever be sold along with any part of the game itself. If it ever is sold, it would have to be separate, to avoid giving the impression it comes with the game as part of how the game is played. It's definitely not how the game is played and never will be, because it's only a way of avoiding playing the game.
