    The last post in this thread seems to suggest there is a problem with an Asset
    https://steamcommunity.com/app/24010/discussions/3/4204742681383682501/

    "This means TSC hits a corrupt blueprint (.bin, which is serialized .xml data) it can't process, which is the fault of the asset provider."

    Try creating the scenario using Only items you have bought thru Steam.
    If you are able to create the scenario than it in one of the other Non-DTG assets you are trying to use.
