Upon some research, many solutions around the web say that it's because the user had their backups folder pointed at /storage/emulated/0/ whereas it should be /storage/emulated/legacy/. First of all, that only applies if you're using the internal memory which I can't because I have 3gb of backups. Also, I tried that and it still didn't work to backup apps (didn't test moving some backups to that location and trying to restore).
I read in other threads that previous ROMs had problems running TiBu altogether so hopefully this is something that will be fixed in an upcoming patch but I was wondering if anyone else was having similar problems or found any workarounds.
