It isn't now because they fixed it. However you can still pause buffer to skip dialogue, which I believe isn't allowed due to splicing potential

Well done

Something I failed to mention, this is also tied to dying. So say you have no saves, you start a new game, and die to Chica (as shown in the video) she will just spawn you in the void if you click retry

If you have a save that you previously reloaded, then clipping out of bounds and falling out of the map will send you back there. I assume it's the safeguard Steel Wool put in so people don't fall forever out of bounds, but you can still fall forever if you don't reload the save. If you end up wrong warping to a different save file, then I believe it counts as a NewGame+ run on the category extensions.
