I heard a lot of people found "troubles" doing this quest. The main reason is because they've been following the old guide so here's one i made :)
following the old quest : http://www.forsaken-...&id=1&record=74 i'll explain the new things.
Step 1: Still the same. You cant warp, to start the quest After talking to snowman in fcity walk right untill you find a house
Step 2: Same. to find her walk top after being teleported
Step 3: Same. to find him get into the bottom red dot in the minimap. ( to know where you are in the map type /where, it will show you your coords)
Step 4: Same. This time you can warp there
Step 5: Same. You can warp here as well
Step 6: Do what you did in step 1
Step 7: Same. Talk to jack. to find him walk top left untill you find a ladder then get on the ladder
Step 8: This time is different. you will have to find a 3rd goblin in xmas_dun01 (@warp xmas_dun01 211 81)
Step 9: Same. warp ice_dun01 47 289 (be sure to loot everything he drops)
Step 10: Same. (as step 3 help your self with /where)
Step 11: Same. just talk to santa
Step 12: Same. santa is situated in the same map as the girl in step 2
Now Talk to santa and get a lot of patient because the items to farm are more
I hope this helps.
