New Update causing issues

Hi, my son is a huge fan of all the sago mini games, and we havent had an issue until now. I installed the most recent update giving access to build the new houses, and now when the vehicle gets to the end of each "board" it just shuts the game off. Completely. As if he hit the home button. Its doing this on the new houses as well as the old. He is super frustrated and crying (only 4, highly emotional). I would give you 5 stars and more on everything you put out...but can you look into this?
