I don't see a problem. Only module that changes the cameras.cam is emtguf's rework. Nothing else in TDW's mod makes changes to cameras.cam.
Make sure this is enabled after the UI mod, and check no other mods in the list conflict with cameras.cam. Maybe disable emtguf's module before enabling this one.
This mod makes no changes to the postioning of the scope, so that's really out of my control.
