Last night I was recompressing the all .pdf files that had "BWV" in the filename (due to me finding out that the compression was sub-optimal), but forgot to check the files after the recompress script completed (too little sleep?)... so now all the BWV files are negatives. But I'm currently reuploading the original files from my backup, so everything should return back to normal in one or two hours.
I apologize for this horrible mistake.
I would like to thank Impy4ever and Funper for bringing this to my attention.
BWV score shown as negatives
