I'm likely a couple weeks too late for this to affect anything within the core rulebook, and I know that the whole project was written simultaneously with the comics and so there was no pre-established canon to base the timeline off of when this would have been written, but I did run into a lore concern while putting together a timeline guide for homebrew makers. There's a huge inconsistency (or open question?) in the core rulebook that feels significant enough to bring up here. On page 008 it states:
Rep-Detect Unit police officer in active duty during 2013–2027...
and on page 152:
Created in 2013 by the United Nations...
This is particularly confusing because:
A) The comics state that Cal Moreaux became the first Blade Runner in 2009
B) No reference is made to the dissolution of the Rep-Detect Unit outside of this passage
C) In 2027, plenty of Nexus-8s would still be active, prohibited, and in need of retirement
D) We know that Ash is an active Blade Runner in 2029 and see an extensive story set during this time
Now, all of that being said, on the Road to 2049 website, which I guess is as close to official as anything else, it does state:
The LAPD activates internal resources to re-establish its Blade Runner unit, tasked with locating rogue Replicants
Which does imply that the unit was dissolved at some point. That being said, this isn't the only inconsistency we see with the comics (the Calantha/Kalanthia mismatch and the state of the Tyrell building in the comics vs. in 2049 are the most glaring—though both easily explained away), but it's a pretty big one because of how central it is to the lore of this world. It's possible I'm missing something from some source or another that explains this, but it all seems very unusual because as far as I can tell, there's no particular reason for Rep-Detect to be dissolved in 2027 to create this contradiction. Ideally the core rulebook could be updated to have the unit created in 2009 and dissolved sometime after 2029.
That being said, if I were to make an attempt at a No-Prize which would allow everything to stay the same, I would say that the term "Blade Runner" was established in 2009 when Cal Moreaux became the first sanctioned replicant bounty hunter in the LAPD. By 2013 the LAPD recognized that the issue had ballooned to the degree there was a need for an official unit within the LAPD and worked with the UN to establish the Rep-Detect Unit. By 2027, with Tyrell Corporation bankrupt and the Replicant Prohibition Act making all production of new replicants illegal, the LAPD decided to kill the Rep-Detect unit and fold Blade Runners back into their other divisions. By the early 2040s, anti-replicant tensions stoked by Nexus-9s replacing most menial workers, combined with the fact that rogue Nexus-8 units were still being found and the issue clearly had not dissipated, lead to the re-instatement of the Rep-Detect Unit.
Did I miss something key, here, or is that explanation about as good as we can get?
