After reaching about level 36 with a very large zoo the APP will no longer allow me to expand so that I can add animals for the next level. Also, after receiving many notifications informing me that zoo babies' births were accellerated by neighbors, I found the births were actually never accelerated. I contacted support and the only thing they could tell me to do was reset the the game and update the APP. I did this even before contacting support and the problem is still there. I contacted support again and they are at a loss as to what is causing the problem and said they would get back to me. Still waiting ... and very frustrated. Also, I noticed that the program tends to crash when I am trying to visit neighboring zoos and I must restart it. Wondering if anyone else has experienced any of these issues.
