I pulled up my Franchise last night, Tuesday in USA, and the challenge was already finished. I can't complain too much, I did contribute a couple of elephant releases on Monday night (CST timing) shortly after the challenge started. But it was only a few 2 or 3. So I can understand how people cold contribute quickly if they already had the elephants in their zoos. I guess I'm just astounded at it being done about 1 day after starting. I am still planning oon contributing a few more, if I pull up my franchise and the calves age up to adulthood.
