Welcome to life as someone who writes.
I lost a chapter once, and since then i have made sure to back up in four different locations as well as printing out hard copies.
And yet still chapter 22 is gone, i remember writing it but i can remember what i wrote exactly.
And i know it existed ti wasn't all though because the word file for chap 22 is there and like Microsoft word it has the first sentence in the part title but the doc is blank and have no hard copy it was also the latest chapter and unfortunately in a style of surreal ranting i cant just think of what i had i don't even remember what direction i took and the worst part is doing a rewrite only made it feel like a phony and despite being 22 chapter in and about 400 out of 700 pages in i have so little enthusiasm to write because i know its wrong.
