It's certainly possible that they did. I get the sense that certain chapters contained plot devices that didn't make any sense, and they had to go back and try to reduce the amount of contradictions.
Changing other peoples' chapters, thus removing the point of a "chain" game? This isn't a community game, you guys. It's a Chain Game, each creator makes whatever they want that fits their style. The plot doesn't need to be cohesive, because it's not like a game made by a group of people, it's a game broken into pieces, each of which are supposed to be made by just one person. (Or team or whatever, if that's their style.) Working out bugs is alright though, those should be worked out. But adding the facesets into each chapter, and changing each chapter's plot?
You guys might as well rename the project, because this is no longer a Chain Game.
edit: also, if you were referring to my chapter, a bunch of what happened was suggested by other people who contributed a chapter. You know what? I still have the full game right up to before I passed it to Erave. I could easily just release it from then. I'll just do that, unless you guys provide a proper explanation for what exactly is going on.
