Question about morphing Star Wars Unleashed
 

I have a bunch of the Star Wars Unleashed "statues" made of plastic. Several of them have morphed under the weight of themselves and do not stand as they should or lean over severely. Anyone have this problem and have a resolution (other than replacing them). The worst of them are Han Solo (on the Falcon ramp), Jango holding back Boba fett, and Anakin and Obi-Wan dueling. Might be a few others too, but those are the worst.

Any suggestions are appreciated.
