Hello!
Thank you for the bug reports. So, the first one, unfortunatley, is a coding error that you have to replay Chapter One to get rid of. The content there is not incredibly important (it is just whether or not you recognize Milo or not). I learned that if I go back in the story to put codes in at a later date, they will not trigger if you have read past is. Obviously, this is something that will be all smoothed out in the final process, but for now, the only way to fix it, is to go back to that choice.
As for the Chapter headers, they for some reason did not go in. I have gotten that changed and during the update tonight, they should be all up to date. Thank you for that one. I didn't even realize it was there. The click button will still say next (due to you needing to remake some code choices) but I have started each chapter with a clear header now that I didn't have before.
