Question [Q] Titanium backup not restoring on stock

I am on SGS3 int i9300 stock rom from sammobile, RECENTLY flashed and rooted it with CF auto root.
All root apps, except Titanium backup, are able to get root access.
For some mysterious reason, Tit backup cannot get root access.
I tried reflashing 2 times again, following the same procedure of philz recovery phone wipe, rom flash, and cf auto root.
No luck. Rebooted countless times.

What do I do?

EDIT: Sometime back, like for 5 minutes, it worked fine, but again on app restart, it failed to get root access.
EDIT 2: Now it is back in business! at 6 46 pm IST.
Now I know it is not a prob with the flashing or rooting part.
