FWIW, Sammy is stuck in purgatory. I got an error message when I put him the DL. But he ended up on the DL. Now I'm getting an error message while trying to take him off. His DL history says "none". But the little red icon next to his name with DL on it makes me think he has been.
So his transition is not seemless. Or seamless. Or even unseemly.
