Comment (by mgalati):

 Kipp - please tell me how to repeat this issue. Are the constraints x <= y
 and y in {0,1} in the subproblem that is being declared unbounded? If the
 constraints x<=y are just in the master and not in the subproblems, then
 your subproblem might still be unbounded without the explicit bounds on x.
 You can use LogDumpModel=2 to see the subproblems.
