There's no such thing as over using a mod unless you intended to break the game, like I said, there's no marker for the trigger, if CDPR would've just put a marker outside the door that says Leave Whoreson Junior's hideout or something instead of meeting Priscilla nobody would think they are done here and fast travel back to Novigrad right away. Besides, free fast travel can be toggled on using console which is technically in the game, don't blame a design flaw on players wanting to save time.
