I was actually watching a video on it. The thing is that one of the major figures at Twin galaxies who was in charge of verifying records was found to have cheated (he got a score on a game that was literally impossible even with perfect frame by frame TAS). So that's when they started looking into these things a bit more closely. It's literally a slight little gap that appears between some of the steel beams. It would be nearly impossible to notice unless you were really examining the whole thing closely.
Yea that's what I remember some weird glitch or whatever at the beams. You have a video that you can put in op. It would be nice if side by side comparison of it loading levels and circling differences. I believe there is something like that on YouTube.
