The camera script gets loaded from the core_camera module, but apparently the core_modloader is loading the mod after the core_camera modules was initialised and thats to late. I build a workaround with a UI app. In order to work you must add the "fixModdedCamerasNotLoading"-app to your UI. The app can also be uses by other developers. It simply triggers a reinitilisation of the core_camera module.
