Some of the last pending upgrades could cost more than your money limit. DON'T WORRY! The next update will always include new vault levels, and you won't have any problems advancing in the game. 

If you reach the upgrade limit, please take in mind that future content updates will include more levels according to the park's size.
 

There's a new content update in the app stores! Download it and discover the new habitat and more dinosaurs! (Please be patient, it could take some extra time until the update reaches 100% of players)
