Is there something wrong with the community challenge? I started some exhibits of animals that say north american, started with artic wolf, american bison, and capuchin. I wasn't positive that the capuchin would count since both north american and south american, but thougth artic wolf would and definitely american bison since that's even in the description of the event. However each species has had offspring in my franchise zoo and not a single one has seemed to count towards the goal.
