Lunar Silver Star Story Touch - (by SoMoGa) - Universal App

[Pitta]

I am curious about something I just noticed.
This last update forced me to download the whole thing again.
The previous update (2 weeks ago) was a delta one.
I obviously prefer the delta one....why this time, for an apparently very minor change, the update wasn't delta too?
Other games did the same thing.

I'm just curious if its some the devs forgot to set up, if it's an Apple fault or of there are other technical reasons.

Many thanks.
