Apple quietly fixed the apps affected by corrupt App Store binaries in an interesting way.
Corruption also happened to us with Carcassonne in february, but only for some countries. Nothing was fixed automatically back then, we needed to push the same binary as another version to fix this, which in turn was expedited and pushed almost immediately. But it meant big useless downloads for users in the countries not affected. Not an ideal situation at all, and we weren't responsible for any of it.
