Blacked out clips in Resolve

Ok, spent a week trying to figure this out so here goes. I'll try to provide as much info as possible.

Just opened up an old project that was started and completed in 14 but have since upgraded to 15.1.1.
Shot DNG and optimized all media to a separate disk. Seems Resolve has lost the ability to find the original clips somehow on the RAID. The clips show up as black in the media pool, timeline and viewer unless I reconnect to the optimized media, at which time I can see them in the media pool, on the timeline but they will not show up in the viewer or of course via the deckling card.

Tried relinking, change folder, all that.

I've revealed in finder and the path is correct there as well. What the hell am I missing here? I have other projects there were created in 14.3 I believe and they are fine once opened up. No problems finding all old media. I really hope this is a stupid moment on my part.

Sierra 10.12.6, i7 4.2GHz, 32GB, GTX 1080.

No drives have been moved or changed as well. Working off internal RAID-0.

I can delete the clip in the media pool, insert it again from the RAID and it appears as it should though that would be insane to do on a feature since all editing, coloring and sound was completed in Resolve.

Hopefully this is an operater headspace and timing issue.

It's an issue -- 15 isn't recognizing dng media in projects created with earlier versions.

There's a workaround of sorts. Delete all the blank dng clips in the media pool, then right click the appropriate timeline thumbnail (the timeline is now all offline clips, thanks to the deleted clips), select import, select additional clips with exact file name match, then navigate to the disk and folder where the original dng clips reside (doesn't have to be the subfolder -- the system will search).

If all goes well, the deleted clips will appear in the Master folder of the media pool and the timeline will be repopulated. There doesn't seem to be any way to get the clips to go back automatically into their original bins, but all your grades and edits should be intact.

Repeat for every affected timeline.

Thanks for the fast response. Multiple Resolve groups had no answer. I figured out your method but being a feature, is a huge pain in the ass. Also I feel like some of the grading is being misinterpreted as well. Contrast and sat are pretty off so it's pretty much a regrade pass on a feature as well.

If this is a real bug, it is a MASSIVE one.

Any tech support guys want to chime in?

It looks like the raw settings are getting lost, on some clips. In your case, it might make more sense to go back to 14 for that project, if you still have the database.
