Not a Poser bug, It's a DAZ screwed up the CR2 bug. You'd think after a year they'd fix it. Just hit restore figure that's [crtl]+[shift]+[F] and it's fixed. If you save the figure here, it will always load right. (That's all DAZ would have to do!) The absolute position of the foot (IK on) does not match the relative (IK off) in the CR2. Poser can't tell which way they intened it to look and guesses ... Wrong in this case.

It does it in every version of Poser. Don't blame SR2
