It may be slightly dry, or, what I do to eliminate cracking; I roll it a bit, then smush the edges back in, all the way around, just push it back in, using one hand to keep it from folding, and the other to push. You will end up with something that looks a bit like a shallow crater, bowl, or dinner plate. Just make sure all the cracks have been smushed. Then roll some more, smushing again as needed. I usually need to do it 2 or 3 times as it gets thinner. Hope this helps (or at least makes sense!)
