The new physical reprint of the Lancer core rulebook has a QR code inside the book that leads to an itch.io key for a digital download. Unfortunately it appears that the key was claimed by an account, which (apparently) should not be possible, meaning that nobody can download the content.
(It's my understanding per the tweet above that Massif sent in a support request about this issue at the end of last month; meanwhile a lot of people in the community are waiting on an update and the community discord is having to field a lot of questions from confused customers.)
The first and most obvious issue is that the key has been claimed but shouldn't be - but perhaps more important in the long-term is that this key being claimable is unintended and suggests a possible bug. After asking around I've heard a couple of stories from different creators about keys being claimed incorrectly, so I figured I'd flag it up as a potential issue.
