Perhaps give a try to Cave Realms / Cave Realms lite, it should be less memory intensive than DF Style Caverns.
It just came to my mind a possible explanation:
Crafting Guide stores the recipes in a database in the world's folder, probably when you switched to the newer game's version it found the old recipes and that's why it shown the older ones instead than the newer.
Good that you reported that unpleasant issue, I can't imagine the amount of people cursing me for breaking their swords on leaves O:-)
This is good to know, if you could try Cave Realms or Cave Realms Lite and tell me if it is less memory intensive, I could create a different branch: Hamlet's Quest + Cave Realms.
That way people having less powerful computers could still enjoy the underground biomes.
