Outside the apartment, when I clicked the cross walk a red car drove up. Then, Rollie got into the car, the car drove away and a mobile GUI came up. However, when I clicked out of the GUI, Rollie appeared in the middle of the screen and after a couple of seconds the car drove up again to pick Rollie up. The mobile GUI came up again as well but this time it wasn't responsive anymore. In fact, there was nothing else to do but to quit the game and start over.
Second time when I tried to recreate the problem, I could choose a destination, but even then, when I clicked the home icon and got redirected back to the apartment, the game was unresponsive again (the hotspots wouldn't show up and mouse clicks wouldn't do anything).
