I had a similar problem, but with hygrophilia deformise. Essentially I moved it, left it out to long, then started "melting" away in the tank.
I don't really think there is much you can do, but if you have one part of the plants not melting, why don't you trim the rotting parts and hope it may grow, however if the roots are rotting, then not much hope ...
