Doctor putricide voice: Goooood neeews everyone we repaired the poisoned client slimed pipe!

Am i alone to sometime open up my game a morning and discover the data has been corrupted so i need to repair file... issue is that when i do so sometime the client just decide to stop working after it finished scanning rather then ''download'' any file at all. Is it an intended bug because while my client run correctly right now i had to attempt the repair several time before it finaly worked.
