This issue works in reverse too it seems, like Rudolf has a quest but I can't get it because his warp message appears instead overriding it, fix this for all npc.

Fixed and live. Cassandra's photo-piece errand was taking over the whole conversation and hiding her other quests. The same problem was on six more NPCs (Boss Kitty, Tylus, Kenta, Jack, Spiegelmann, Cesar); all of them now show their full quest list with the special task as one option, and an automatic check stops any NPC doing this again.

Rudolf part is fixed and live now too. Roodolph's sleigh ride was answering every click before his quests got a look in, so Warm Milk Delivery could never be picked up. Now when he has a quest for you, clicking him opens his quest list with the ride as one option ("Take me to the Snow Sprinkler." / "Take me back to Happyville."); with no quest to show he just offers the ride like before. Same change covers every NPC whose only script is a ride, including the Christmas tree Snowmen in Happyville. To re-test: Happyville, click Roodolph, you should see Warm Milk Delivery and the ride in one menu.
