HAHAHAHAHA! 
No. I have a waterfall of "Errant Draft X" files in a google drive folder. Because when I make big changes to the story going forward, I keep the old draft and make a new file, but obviously I start from where the story has reached already rather than pasting in stuff I already got past.
So there is no one file where you could read Errant in its entirety. 
Current draft, for anyone wondering is called "Errant Lucky Draft 13", and it has actually been quite lucky, it's been one of the longest ongoing drafts without me starting a new file!
