    Hi Jørgen,

    Please excuse not getting to you for so long. Currently, it is possible that the NodeCount attribute reports 0 although a B&B line has been printed, i.e., the root node has been solved. This will no longer be the case in a future release and the root node will be properly included in the node count. The NodeCount attribute will only show 0 when the problem has been solved in presolve, i.e., no nodes have been opened. Thank you for reporting this.

    Best regards,
    Jaromił
