Zookeeper's Lounge

There is a glitch in my game, my giraffes and crocodile always escape and I don't know why.I think the problem may be a download or a glitch but Im not sure.And when the animals escape,they just escape and the guests don't fear them,and the zookeepers don't do anything about it,the good thing is that the animalsd don't attack either.
Look at this

I think I found the problem!
My Gembosks escape also and the animals that escape don't have a gate for the zookeeper so I yhink that's why they escape but Im not sure yet.

Yeah, I think it is a glitch in the game....I have had this problem with all sorts of animals - cheetahs, especially. Hopefully this will be addressed in the new expansion and will be fixed. It certainly is annoying!
