Rancher, you "know without a doubt that what you saw was true" as much as Puggo did. Its called a false memory, and its a common, everyday occurance. You remember seeing footage of the Rebels fighting the Wompas, but no such footage ever existed, nor found its way into a film. You are remembering things that are impossible because they were never filmed. It is common to mis-remember things from your childhood--things you swear you saw, that even when you remember it now are there clear as day. I'll repeat, its common, and there are various people within this very thread that "know they saw without a doubt" a certain thing, but years later was just proved to be a delusion. The cut you saw, being 70mm, was indeed different from 35mm prints, but in extremely minor and insignificant ways, thus perhaps planting the seed in your brain that the film was different but then being confused with information gleaned elsewhere. The wompa scenes appeared in trading cards and in the comic books, in stills and publicity photos, they are even prominently featured in the Star Wars Trilogy Arcade Game shooter from 2001 or so. I went into this before about how the inclusion of such scenes as this and General Veers death would require massive measures to be taken, and would not have accidentally "gotten out" and only witnessed by a nine year old and his buddy. The Bacta tank sequence appears to have a shot missing which radically changes the structure, and there are aleternate shot composites and missing wipes, so I'm sure these made you realise that something about the 70mm was changed but in trying to determine what it was your mind just remembered all kinds of stuff that was never in the film in the first place.
