I would strongly recommend you upload your old save that seems stuck to the wiki or another forum. If something is missing, someone could help you with it. If there's a bug, I'd like to be able to fix it.
Funny thing there also.. I kind of saved over the old save.. I do have others but, that's right before the war. I figured I should start anew since after seeing the wiki. I found out I missed quite a bit. Including Atlina and several others and of course the lust plate. But to go so far without any of that compared to others? I think I did well. I have a tendency of using 2-4 save slots if there's choices in the plots, moral and unmoral routes. One save dominated Varia, where as, the other reshaped her. Then I came across the war and saved right before it in a 3rd slot while using the moral save.
I did a few tests with the older saves before the 3rd Arclent war was bugged. After progressing the new save past the 3rd arclent war. It seems that during the old saves of missing a few things(atlina, lust plate, and a few others). During the petitions right after, Wynn wasn't present during the old saves but was present during the new save. So, all in all I'm able to progress again, thankfully.
