My Christmas challenges unlocked. Also only unlocked to abundant toy storage. What do I do?
There's always quests to VISIT the Challanges in order to unlock them.
check your quest list, talk to npcs in camp and the last location you unlocked, make sure you've placed all the puppies (or other quest items) you gathered...
