Are you able to change it back at character selection (alternate appearance button in the bottom right)? One of mine got stuck in SOGA when I created a new character, probably because the game now considers SOGA to be default and forces it upon you at creation, and when I made another Dark Elf it set me as wanting my Dark Elves to be SOGA... so it made all my Dark Elves forcibly SOGA. Went through and changed them all back, but it ticked me off quite a bit... and I still cannot understand what possessed them to consider the poorly made SOGA models the 'best' ones that new players would be introduced to at character creation. Ugh.
Hope you can get your character back to normal.
