That is weird. I wonder why it isn't working properly for you. Did Kayo at least battle you & Sydney give you cut? If she does, that should trigger the pink haired woman to disappear from blocking your path to battle the 3rd gym leader in Mystic Falls.
EDIT: If you still can't move on, PM me & I'll send you a direct copy of the hack that has the working event. I just played through it & it worked perfectly. (Btw, try after patching it again with the updated rom in the main post, to leave the ship completely. Then return back after entering a poke center.)
