In case you don't work it out, you are missing
22-CH-2-3
You can tell because you don't have any 22 file with Annie (2) or Oswald (3) present in it, and you know from 22-LI-1 that Oswald doesn't die until midway through scene 22.
As always, spoilers!!! Please do not look beyond this point if you do not wish to be spoiled!
Yes!!! I did actually find it! Thank you so much. I went to pull out my Act 4 chart and realized I got too excited when John remembered Annie at the chapel so I immediately went onto that scene. In hindsight, it did seem a little odd how Annie just came to these sudden conclusions. I just erroneously inferred Oswald was dead and when Annie died, I miscounted the bodies. Oswald did die but not in the scene I thought he did. But yes, when I looked back at Act 4, I did see a blank spot as you said which made me realize my big, big error. It didn't help that I was hyper fixated on the belief that there was a death in 00 and thus I focused all my attention on my Act 1 chart.
I feel so relieved now. I kept looking for the wrong missing body and all in the wrong places. What a lovely game this was. Thank you so much for all your help because I wasn't able to stop thinking about what I was missing.
