Inverse Kinematics only works once on a new rig before bugging

[Local_OverJ (OverJ)]

As you can see here, the leg will adjust for the foot’s position, working as intended (seemingly).

Then, once I stop moving it for the first time, It starts to bug and works as if I did not have Inverse Kinematics on.

As you can see, I want to to function as if Inverse Kinematics was on normally.

Bumping so people can see it, still haven’t found a solution.
