hello

funny thing is I recently faced this problem which is new to me and never seen it before.
I have created a joint set for a leg from hip to toe.
then I use the RP IK and connected the hip joint to ankle
then I created a reverse foot joint set
now when I parent the IK handle to anything specially the joint IK handle moves and I have to move it back to its original place.. I have been setting up characters for long but now I saw this problem which I have no idea where it came from
anyone knows what is hapening here?
