Not EVEN going to get into the Original VS SOGA model debate (other than saying I'm very happy there are not 2 models for any of the 4 newer races).
As for the original comment, if you go to character select and try to create a new character, whichever race/sex it randomly opens to when you hit "create new character" is going to get set to SOGA in your options as well as the race/sex you actually end up picking if it has a SOGA model.
Likewise if you run with SOGA and switch to original models to alter the original model, that race/sex gets stuck on the original model.
Usually you can fix it in the options on the character screen.
Sometimes it even gets stuck that way in your in game options. The check box for that race/sex combo will be greyed out and you can't change it from whichever one it got stuck on. When you mouse over it, a tooltip pops up saying "player settings have overriden" something or another.
I've bugged this more than one time. The first time was when they first put the defaulting to SOGA models in.
It's probably not very high up their list of things to do, but I know if my girls had gotten stuck in the model I dislike, I doubt I'd continue paying & playing until the bug was fixed. Lucky me the character I've had affected by the everstuck can't override settings got stuck in the model I prefer. I'd like to be able to see the other one on occassion, but I'll live. It is still a bug that is really annoying, been around a while and needs to get fixed.
