Default Tab-only apps

Wondering if anybody else has run into this. I have a few apps I can't restore via Titanium Backup due to the "Tablet mode only" warning on the PadFone X. That's fine, they normally install anyway via Play Store. But I cannot get Surgeon Simulator to install- ASUS gives that warning, and then the Play Store errors out with a -15, then an unknown error, while the status bar reports successful install. Anybody else having this issue?

EDIT: Correction, PS Touch and Osmos HD are both also now failing to install, same thing.

EDIT 2: The last two apps installed fine now. Surgeon Simulator downloaded 230MB or whatever it was and failed out. Now, it only downloads 10.34MB and returns error -15, as well as "invalid resource URI".

EDIT 3: Through logcat sleuthing and rapid refreshing of files, I've figured out that it's not specifically PadFone that's doing this. It's just not downloading the complete APK to the device.

EDIT 4: DOWNGRADING to a much OLDER Play Store version resolves it. WTF?
