I'm not quite sure what you're describing...?
Are you saying that the big Jade Leaf dried up and withered, leaving only the new Jade that grew from it?
Any chance that you could post a picture?

I was thinking same thing as Josh. If the 'mother leaf' is dried up and fell off the new little plant then that is just fine, it is the normal process. The new plant should have roots of it own and fend for itself now:)
