BUG: Lost Grade during edit, can't copy grade from still

Hi

Love most things about Resolve 17 but ran in to a few major bugs tonight. After spending a couple hours on a fairly involved color grade (10 nodes, lots of power windows and qualifiers), I finished the grade and was trying to keyframe it to fade in halfway through the shot.

Suddenly when I tried to play it back I lost all of my changes, with the grade turned on it was the same as the raw, uncolored shot, except there was a weird blocky pixelation and loss of contrast across most of the image. Toggling the grade off got rid of it, but it came back when toggled on. My node tree was still there, but all information from each node was erased except for power windows

I thought I lost all my work but was able to get most of it back by loading an earlier back up. Shot was able to export fine and looks good. Now I'm attempting to copy the grade on to another shot using a Still, but now it just copies the node tree but all the nodes are blank

Can u reload the old project, then save a still and make that a powergrade?

Hi Peter

After quitting Resolve and reloading the program, I was able to copy the grade from the still as normal. Guess it was just some buggy beta performance, but I figured you guys could use the info.

Thanks!
