These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Holograms are projections of light. They cannot be destroyed (partially or fully) by going into a place that cannot sustain the image (i.e. outside), much like a movie on the silver screen is not destroyed if it is projected onto thin air.
Holograms are merely avatars. Even if it were somehow possible to "damage" or "destroy" holograms, it would have absolutely no effect on the actual program. The data for the 3D model would remain intact; it should never be necessary to remodel anything unless you forget to save.
