Fixing a multi-timeline project, most restored but one timeline, having issues.

I began this project a couple of years ago and finally got around to editing on it last year and recently, did an update video to let folks know what was up since the last video almost 2.5 years ago and last month, noticed my cache drive was full, so deleted it.

Up to then, I was doing a prolonged preproduction by adding stills, graphics (and building), getting attributes and even did a 3 days of shooting clips of various parts of the community (it's my old stomping grounds, growing up). The images were intact for each timeline, but some of the audio was unlinked (red) in both the media pool and on the timelines in places.

Not thinking then that it may contain audio files for said project and many links were lost, not all, but parts of several timelines had no links to the audio files. Well, I was able to manually find them by rooting in File Explorer but had initial issues with figuring out how to get them back into the media pool and relink.

Yesterday (2/22), I figured that out and had to do each timeline individually and they just linked up, edits and all as if nothing ever had happened.

This meant finding some in the C drive and other drives, then realized what if they are in the recycle bin? Sure enough, rooting around, I was able to find them in the cache folder in there, so restored them and I believe they all resynched back up automagically and now the first timeline where I talk about how the community began, the first several audio clips are still red and I think I found them, and they are in the media pool, but I can't get the timeline itself to see them. They do not show edit points so maybe not correct?

They are voiceovers directly in Davinci Resolve so the clips I generated by cutting out dead fluff, ripple deleting to bring parts together, then adding the video to it as a combination of stills (animated in/out) to the VO track and on one timeline, video footage I had shot in early fall 2024. The project is far from done, but I have several timelines done and will need to stitch them together to make the final project.

At the time I was editing this, I had Davinci 19 on a new build I put together in January 2025 initially, then mid project, upgraded to Davinci 20 for ease of not having to patch for VO work as I had a devil of a time getting 19 to reliably patch correctly much of the time.

Currently run Davinci Resolve 20.3, Bld 13 on a Core 7 Ultra PC with 64GB of RAM and the Intel A770 graphics card and the project is 4K and use Windows 11 Pro.

So the question is, any suggestions for how to get audio to link up to timeline in this one timeline in the project? It looks like everything is there in video assets as far as audio goes in the media pool. I do have backups enabled etc, but sadly, older backups are gone as far as I know. The backups now look to be this month, instead of earlier iterations.

Thanks in advance.
