Default [Q] 98.18.94 keeps failing

I'm on 98.18.78, unfroze all my apps (I use App Quarantine, not Ti, never had any issues) and temporarily removed root with Voodoo but the update just won't take/keeps failing.

I've read that there isn't any significant difference between .78 and .94 so I might just stick it out until KitKat in the following weeks, but I'm hoping I won't have any install issues once that update comes around.

Do you have any suggestions to try or explanations for why it won't stick?
