I started building a zoo and after about 2 hours I decided to open it and no guests are spawning. I checked the spawn points and nothing...The park is Open and it has facilities, habitats, food, drink. I just don't understand. Also, when I go to place habitats down the game crashes and I lose my mouse cursor and I can't do anything. I have to restart the game. The game is unplayable at this point for me. Anyone else having similar issues?
