Well you already tried most of the obvious solutions and since your problem did not get fixed it seems it might be a case of corrupt save file. As a last resort make a backup of your game and then reinstall it but do not restore the data. Play from the beginning for a while and see if you are still getting this issue. If its still there then you will have to contact Gameloft's customer support for a solution.
