    Hi Kianoush,

    This indeed seems suspicious. Could you generate a minimal working example to reproduce the issue? You could write your master model and the Bender's submodels you solve to LP/MPS files using the write method. You can then generate a short program where you solve the master model and the submodels in your callback. You can read the model via the read method.

    Best regards,
