From your game log, it doesn't look like you did the subway quest before...
As for the Pumpkin King, there is a problem with the cooldowns with the server (developer work), which should be fixed I believe next client release (I'm not sure if the update can be made live without a client update), so you will have to be patient with that one.
Well it can't just be that simple, I've done the quest. It has to be a update rollback bug. I know i did the subway quest and even if i was willing to re-do it, i can't! Yorkie doesn't let me, he just talks about the Nocturnal Feather because I've already completed the quest. I talked to Yorkie and i found his brother on the small island on route 21 and bought the parcel from him and gave it to Yorkie. I even used the subway before, but only once and then i moved onto Hoenn. :confused: :Nervous:
