If in doubt...clean it out. The cost(s) and time for repair will(would) definitely be more than the time to clean it out.
I buy all my clay in the fall and purposely let it freeze in the winter as it seems to age the clay. Although I have to wedge it all in the spring, I don't mind as the texture changes after the freeze. The clay also seems to change shape some in the bags so I would be afraid that the frreze/thaw cycle would damage your pugger in some way.
Enjoy the warm weather! 4" of snow here, this AM, covered up our brown Christmas - if only the snow would learn to stay off the sidewalks and roads!!
