I'm still having issues with Titanium Backup (not baked in the kitchen, but installed from the Play Store) not wanting to continue with restoring apps when using MCR, even with updating to Jr7 and doing a wipe beforehand. I can't tell if the size of the app being restored is an issue or not, but when I do a restore of an app, it'll say it's restoring but doesn't seem to be doing anything. This happens both when restoring a single app or trying to do a batch restore. Restoring data is fine. I've only had this issue with MCR ROMs on the Nexus 7, I did not have these issues on Stock or any other ROMs (like the CM 10 or AOSP based ROMs). I had thought that maybe the issue was something to do with which Superuser was being used, but the issue comes up regardless of using ChainsDD's Superuser or Chainfire's SuperSU.
