I ended up getting hit by it a few days ago as well.
I unlocked an Asari Vanguard as well as other stuff like the Geth Plasma Shotgun, Black Widow, etc.
The same thing occured as everyone else -- the bonus pack and the character not being unlocked anymore.
I haven't lost any XP or items yet, as I'm still playing with the character hoping to re-unlock it to see if it fixes things in the meantime. As I understand it, as soon as I switch to another character, I'll lose all the items and the character.
Anyways, just wanted to add my name to the list. Good luck!
EDIT: Xbox 360 version
