So can YOU tell me what the hell happened other than "Oh, we got bored with Tir so we had the rebels win."?! It's been bugging the hell out of me.
The Tir Tairngire you see in Shadows of North America had two ironclad directives:
1. Incorporate the events of Mike Mulvihill's novel, Private Agenda. This includes the Lofwyr/Aithne/Oakforest/Hestaby business. I think a summary or something was posted at one time explaining the Machiavellian events, but the novel itself was never released. Core events of the Salish-Shidhe were also driven by a novel (which I doubt made Andy Frades any happier than it made me).
2. Make it more playable. I do not recall seeing other proposals for the Tir so I'm not sure what other ideas people had cooked up. If you take a look at the original Tir Tairngire book (written by Nigel Findley himself in 1993) you'll find that the entire book is pretty much about spreading more Earthdawn connections and the description of a location at odds with the themes of Shadowrun (e.g. it had impenetrable borders, superman special ops, mystic sites of world shattering opaqueness, deadly efficient internal security, no extraterritorial megacorps, and was a nexus of Immortal Elf shenanigans!). I decided economic collapse made the most sense.
[ Spoiler ]
If I had known the events would be wrapped up so fast I would have had Rinelle overthrow the government in a glorified Orange Revolution. It was intended to act as a longer-term plot point for shadowrunners operating in the region (Stick it to the Princes? Or lord over the commoners as a hired enforcer?), which is why in SoNA it was written to sound like there was an actual guerrilla war going on (and a particularly vicious one at that, given who the elves behind the throne were). Yet the major upheaval was in 2062, with the Rinelle issue wrapped up by 2063. That was not the design intent or the assumptions I was operating under.
An Aside on Ehran
I REALLY liked the character of Ehran - he's the only metacharacter in the entire Tir I felt mattered outside of the immediate story narrative. I could never shake the feeling that the canny old bastard was up to something really devious and didn't let the Lofwyr/Hestaby bulldrek cloud his mind for long. I wonder what he's up to now besides playing Extreme World of Warcraft ...
(Disclaimer: I really liked Rex as well, but the outlier metaraces get no play ).
EVENTS OF NOTE SINCE SHADOWS OF NORTH AMERICA
The official pronunciation for Tir Tairngire is shir sha-irn-gi-rā (Sixth World Atlas, p190).
Loose Alliances - Set in 2064
-- (p. 27) Communist policlub: People's Labor Front.
-- (p. 44) I'm not sure what Harly means by "Elven fascists! Now that has got to be the funniest thing I've read in a long time."
-- (p. 53) Good brief on Rinelee ke'Tesrae. Not sure about "millions took to the streets" given the population of Tir Tairngire. Revealed that Cyril Le'Fien took the seat vacated when Feana was assassinated (paladin devoted to ecology and a geomancer. Trained by Ehran).

State of the Art 2064 - Set in 2064
-- (p. 14) Intelligence alliance with Japan and Pueblo. Tir specializes in magical espionage. (Brief aside, but the IMINT capabilities of Shadowrun satellites are laughably bad in overall capability (no hyperspectral or LiDAR?) -- but crazy optimistic in visible-band resolution for some reason (read a bar-code from orbit?)).
-- (p. 22) Information Secretariat covered. Good info here.
-- (pp. 160-161) Feana Sterling and James Telestrian III take the vacated seats on the Council of Princes. Sterling quickly assassinated by Rinelle Jenna Ni-Fairra goes apeshit. Failed attempt on Jonathon Reed. Horizon Group hired by Surehand (with nudging of Hestaby).
