Escape message - bug?

[shirandhak]

In challenge canada I get repeatedly the message that there was a dino-escape and my rating has dropped from 4.5 stars to 1 star because of that. But all dinos are in their enclosures. What's up there? What do I miss?

Edit: My 5 Dilophosauri are endangering the guests, it says. But why? I have a tour through their enclosure and the enclosure is intact. But I have a tour through the enclosure of my ceratosauri as well, and they are no danger for the guests.
???

Ok, never mind. It was my own fault. Seems like I dropped one healed dilopho too near to the fence, so it got stuck half in and half out of the enclosure.
