I heard you like patches, so here's a patch to patch the previous patch that was supposed to patch another thing I hoped I already patched. Patch.
In seriousness, it seems like dialogue logic handling rewrites worked well, but loading got back to the start of the scene instead of the specific line you saved at, so I managed to restore that feature to fit new logic. Hopefully I didn't break anything else in the process.
As usual, let me know if anything breaks for you and I'll try looking into it :)
