Creatures Caves

My wolfling world semi-corrupted itself when I loaded it up this morning. Somehow, I managed to get it working just long enough to export all my norns (and seconds later, the world died completely)

So I went back to an earlier version of the world, but now my Chronicles doesn't show any stats. It only tracks "time elapsed". Everything else, like "current norns", "eggs", etc, remains at 0 even if I import a creature.

Edit: Oh, but it DOES show information in the History tab, just not the Statistics one.

Does anyone know what file it's looking for in the backups? I have copies of GameLog and they appear to be full of creature information, but the game isn't picking it up.
