Editing SubModule.xml

For the options to work, you should include the additional SubModule that Bannerlord.MBOptionScreen provides

    <SubModule>
      <Name value="MBOptionScreen" />
      <DLLName value="MBOptionScreen.dll" />
      <SubModuleClassType value="MBOptionScreen.MBOptionScreenSubModule" />
      <Tags>
        <Tag key="DedicatedServerType" value="none" />
        <Tag key="IsNoRenderModeElement" value="false" />
      </Tags>
    </SubModule>
