It seems to me that it happens all the time in my games. Cartage seems determined to take Carthago Nova and Lepcis Magna and often looses Caralis early and eventually even Sicily. The main thing bothering me is that they are too easily overrun in Africa, usually to the Scipii. Come to think of it I have personally not seen Carthage live beyond 230-220bc in any game and where is her uber-fleets, haven´t seen those either. Someone should mod this to let her start with a dockyard and more elphant-troops etc.
