Wallpaper reverted to FP default after backing up using Titanium

I had one of my photos set to be used as my wallpaper. I just backed up apps + data using Titanium Backup (free version). When I closed it after I got the notification that it was finished, my wallpaper had disappeared. Now it’s one of the fairphone wallpapers. What the heck?
FWIW: FP1, 1.6 with unified storage and google apps installed.

Interesting. I never had this. Don’t know what might cause this - same config here. Are you using other apps to manage wallpapers?

If you reboot after the backup, does the wallpaper restore itself to your custom one?

Hi Chris, thanks for the reply. Unfortunately, no. Titanium has given me no end of problems, so I’ll be looking for another backup service.
