Copy paste my presets ruined my entire gallery!

[defaultfv0nbqi8568x]

Hi,

just had 5h work gone in one bug in LR classic. I was copy/pasting my preset (using the command+shift+c) to my next picture, and did not see a whole bunch of pictures were selected. My preset was applied to the whole selection.... BUT....in the meantime, LR classic (latest version 12.1) crashed and I could NOT undo this mistake (selecting my full gallery).

 now, my WHOLE gallery has got this preset and overwrote all my former editing.... when I restarted LR, all my gallery was edited with new preset aynd ruined 5h of my work!!!!

Is there a way to get my forer edit back?

thanks for your support

You could check History, although it'll be a pain to go through each photos and drop back to before the preset was applied.
