I am finding it impossible to finish this scenario even though I have completed all the requirements. I have second-. third-. and even fourth-generation animals in my zoo! I have had every kind of combination of breeding, including the hardest kind where, for example, Zebra Grandpa and Zebra Grandma mate a few times and have Zebra Mom and Dad, and then Zebra Mom and Dad mate and have Zebra Kids, etc. The animals just keep mating and the scenario never ends. I've tried starting a new scenario and the same thing happens.
It is EXTREMELY frustrating. I contacted Microsoft Tech Support, who have been very nice and helpful, and per their instructions I did a clean install of the game. I did not patch it this time. Unfortunately I was still unable to win in my saved games but I plan to start the scenario a third time and hopefully that will do it.
If not, I'm at a real loss, because I can't get to the Mysterious Panda and seriously, there's only so many times I can start a scenario over again, especially when I've already "won" it twice!
Anyone else had this problem? I assure you, it is not a question of satisfying the scenario requirements. The game shows "goal achieved" when my lemurs, zebras, and chimps each mate for the first time, but after that it's like I'm playing freeform. Grr!
