This just happened to my bullpen on a new team, the whole staff got placed on reserve and swapped with existing players, so the bullpen and all of my recent changes.
SO currently no bullpen and swapped out existing starters for three players on my reserve roster.
Looks like all of the cards I bought in the AH earlier, then submitted to the server after changing around my team reverted to the reserve roster.
My Manager name is Ditka on this one, still in the Entry Pool.
EDIT: Tried to post images, failed horribly
