Same. Mine was a 6 year world. Luckily I have backups, but all mobs accross the world, regardless of being in unrendered chunks, died. All books deleted, signs erased, banners reverting to a plain black banner, command block commands, erased. But it also raised my coords up by 65 blocks, making 62 sea level become 127 on my Y.
