I have Android version 2.4, and i have frequent messages saying "Unable to download game files"

during loading screen before a race (when changing from 2G to 3G network), and that's fine.

I can understand that game needs to download some files for a race, and it simply returns to race selection screen.

But what on earth is the problem when i start race, and drive 5 laps without problems, only to receive a message "Unable to download game files" in a middle of a race, and it just crashes to race selection screen !!!

FM, how is this possible ?!!  And why these downloads for an offline race, WITHOUT player names, ghost times and custom paint jobs ???

It happened also in 2.2, and 2.3 version.

And yes, i have all assets downloaded.
