Creatures Caves

Oh boy, will my problems ever end?
I've been playing lots of C3 docked with DS lately, but yesterday something went awry. While installing a crapload of agents and breeds, somehow my world was reverted back to how it was the first time I saved. I figured it was a one time error and played for about six hours straight, only to find that, today, it saved none of that. I've just gone in and tested things, and every one of my worlds is refusing to save after about an hour of play. Or, in other words, the worlds are reverting back to the one-hour save point.

The changes that occurred that day were...
I changed the shortcut on my desktop from InstallBlast.exe to Engine.exe; I installed the Fimbul Norns and Dream Norns (I'm pretty sure there were more, but I can't remember them at the moment.); I installed the Cupid's Lyre; Candyfruit; Interporter DS; Moe's 2009 Advent pack; the C3 Snowblower, Mistletoe, and Snowman; C12DS.

In the first world I was playing in, I had injected Chione; the Dust Devil Grendels and their agents; Light Rune; CCSF Norn Dolly; Survivor Coconut Dolly; Interporters; Norn Nip; Mistletoe; Pixiefloss Norns; Desert Nursery; Sunflowers; Candyfruit; Creature Counter; Stop Slapping Creatures DS; Creatures Crossbreeding; C12DS Login Bypass; Magic Words Core; Magic Words Love/War Time; Magic Words Symbols; Colotrue Ettins.

I just hope C4 doesn't have this many errors when it comes out...
