Well, I feel somewhat akin to Oedipus right now. Not because I'm guilty of patricide and incest (shut up! gross!) but because the knitting gods have chosen this moment to knock back a few beers and have a giggle at my expense.
I was fewer than ten rows from the end of the first repeat of the Wedding Ring Shawl center when I noticed something. See the little green arrow?

It's pointing to the row I skipped. Yup. Just skipped right over it. Didn't knit it at all. Left it out. Golly! Whoops!
That row mostly serves to put a space between the two beads inside the lozenge, so I didn't notice anything was goofy until I'd worked half the second row of lozenges in the repeat.
Then I said something emphatic and unsuitable for general audiences that rhymes with "Truck! Pluck! You smother clucking Tina Yotherbucker! What the ducking plucking truck! Zit! Zit!"
I could keep knitting, and chances are nobody would ever notice. But I would notice. I'd spread out the finished piece and the absence of that row would be the only thing I'd notice.
So, bloody but unbowed, I rip. This is an epic project; I'll do it well or not at all. It is the mature way. The noble way.
And if you tell me I should have used lifelines so help me beeotch I will gouge your piggy eyes out with my own two thumbs.
