Is there a way to make Houdini automagically see when a cache has been deleted from a scene, or a texture file on the HD is adjusted ?

I've been running into issues with adjusted textures not refreshing, or Houdini holding on to Alembic files that have been deleted from a scene until I close Houdini.

One would expect a smart app like Houdini to automatically take care of stuff like this. So me thinks there might be a preference that needs to be set ?
