This isn't a Wiki glitch.....its hiddden bonuses missing from maps.
In relation to Halloween 2014 in the game mine Pumpkin Realm....there is a note under the Event Total Summary that states:
To get 10 Gems, 1 Green Ring & 1 Witches Hat you need to roll the pumpkins on deer skulls......this isn't marked on the maps.
Not sure if these hidden bonuses form part of the "Event Total Summary" of 19 Gems, 1 Green Ring & 82 Witches Hats....or if they are additional to & on top of them.
In relation to Christmas 2015 in relation to the game mine Illinois Airport there is a hidden bonus of 1 Green Ring & 1000 Experience if you put 4 shopping trolleys on the water puddles....this isn't marked on the maps.
Not sure if this hidden bonus form part of the "Event Total Summary" of 2 Green Rings.....or if it is additional to them.
