From Jay: Since the first person said the crash occurs on starting a saved game, it would not be the language crash problem. They gave JPOGItems.ztd as a possible cause. Although that file has problems, I do not believe they are problems that would cause a crash, at least from doing a quick look at its configuration. It might be the crash that occurs when an object in the zoo is changed from one that the guests go to look at to an object that the guests do not go to look at. There is a topic at DG that lists causes of ZT crashes and how to avoid them, including the one I just mentioned as well as the language crash problem. http://www.ztcdd.org/DG/index.php?topic=5452.0
