After the last update I wanted to take a look at what that GW was, so I clicked on the tab, skipped the message saying I need Quicktime, and then had a choice of the four factions.
I clicked one, and it said something like "You can still change it, but clicking on 'Finish' makes it final".
Then I looked at the other ones, last was the Seraphim i believe, but I pressed "cancel" because I didn't want to commit to a faction just yet.
Immediately after that a modal popup came that read "Avatar Name Generation", with a name, and two buttons: "reset" and "ok".
A name it proposes is "Paladin Hyddeir Olwen", so I guess that's Seraphim?
The only way getting out of that popup without clicking ok is killing the FAF process.
Whenever I go back to the GW tab, the popup comes back.
So I never clicked on "finish", and now it seems I'm stuck with the Seraphim anyway, even though I didn't choose them.
Can I never change my faction ever again?
EDIT: Forgot to add forever.log
I believe the interesting part is around 21:06:45
