Everything looks fine to us, except for the WereShroom location. The Frozen Falls are completely blocked off by a blizzard and will be so until a certain plot point appears. Our suggestion is this very unsuspicious bridge that doesn't even have a name that has a nice cold climate, it's also rather dangerous as it's close to a werewolf territory (and it fits since WereShrooms, Werewolves...)

Otherwise you're all good to go.
