Sometimes when the game crashes, it happens to be in the middle of re-writing one of the Superblocks. When this happens, the superblock data file is incomplete, and the next time the game loads, it will find that it cannot load that part of the map, so it re-generates new terrain. This is called the "Terrain regen bug".

Your only hope to recover from it is if you never updated your iPad to iOS 5 or later (the update that came out about a year ago when Apple introduced "iCloud") and if you have been syncing and backing up your iPad to a Mac or a PC using iTunes. If so, then you can use iTunes to restore your iPad from the latest backup. Plug the iPad into iTunes, and cancel the sync as soon as it starts. Then select the "restore from backup" button. But this will lose any other recent stuff you did on your iPad since whenever that backup was made, and it only works if you're still on iOS 4 or earlier.
