Post #811 solves this problem, also mentioned in step 7 of the Nutaku part of the troubleshooting guide.
Edit 1: Updated to include both DLpy scripts, the troubleshooting guide (mentions the newest DLpy script location), attached the DMM files for Gawain [Work Ready] and [Memorial0026] Osiris. The previous DMM files are on
post #857.
Edit 2: Updated to include a
pixeldrain link to the full portraits of the memorial illustrations from a
Japanese wiki. I've converted the WebP files to PNG files and added in empty space around the 960x640px images to make them 1440x960px.
