Hi there! Sorry for the late answer, and thank you so much for answering. I haven't tried the cheat code since I don't want to cheat. If there's no fix to this, I guess I have to cheat, but I'll wait a little bit longer and see if there's a new bug update soon.
Sadly there won't be any more updates to this game. The goal for this game was to have it played on GTLive. Now that they finished it I don't need to polish the bugs anymore.
I also need to choose a point at which I stop adding to this game, because I could sit all year and make updates to it, but I want to focus on other projects.
