Lost all progress iPad app

[Jimsocks]

I had every ship and layout unlocked, and nearly every achievement unlocked too. I started up the app to play a round on a random ship and POOF! The app has forgotten I've ever even played!

I checked Game Center and it too seems to think I've never played.

Nothing has happened to the iPad except the sun outside set and rose again, and shazaam- no more game data. Super upset!

Is there anything I can do? I haven't done a backup in eons.
