Hello there!
I wanted to have a look back on some of the Hallowjack/Grim Arlequin Motifs after obtaining them yesterday, but I didn't find them in my Eidetic Memory. I am playing in French. Yesterday evening, I was dancing feverishly around corpse of a defeated delve boss with some other people who seem to play in English, and they told me that they saw the Motifs in their library, so it might be a "language-exclusive" bug. (Or I might just have failed to look well for it.)
Last week, I also didn't find the Yokudan motif that you can obtain in Craglorn within the Eidetic Memory, and for a long time, the Order of the Hour Motif appeared blank on my library, but I didn't think about checking whether it was still the case last night.
