The game has had some rounding issues with the distances since they quartered them — seems to be a bug due to a difference between the distance meter bar and actual counter? I’ve noticed especially when you walk near exactly 1.25 km into the candy distance. Don’t worry, the negative corrects itself when the distance next updates (or you can turn the game off and on again), and the candy count always seems to be okay. It’s the candies that you care about anyway. Just another minor text fix needed.
Spectacular day everywhere! I’ve definitely done my walking buddy proud this event — I won’t be able to max her out, but I will have walked 100 km by the time the event ends tomorrow. One more set of 12 candies and my Blissey will be over 3100. Good enough!
