As seen on the screenshot. The same settings have been used in all images, but some turned out pink. This wasn’t the only case… many times copy/paste results in horrible color cast on different images. I tried turning off ALL modules and the cast remained until I deleted history stack.
SImply copy settings from one image to another lead to pink image. And as mentioned above, BW module reset solves this problem.
And it’s not a problem with different ISO. It happens also on the copy of the same image.
Thats no bug - by copying the whole history stack you also copy the black/whitepoint and maybe clipping settings in highlight reconstruction. The white point sets the value for clipping highlights. If source and target were shot with the same camera and same iso value that is ok; if not you“d better use shift+ctrl+v to insert the settings and deselect at least raw black/whitepoint.
