IKTarget missing (Blender)

I am trying to animate a back strafing animation with an R15 rig I found on the dev forum (probably outdated for practical use in studio), but while I was animating, I noticed that the right foot IKTarget was missing (I used it before). Does anybody know what happened because I thought I hid at first but I can’t find any trace of it which leads me to believe I deleted it.

(Left foot has a box, Right foot doesn’t)


(For reference, the left foot IKTarget is “LeftLowerLeg-IKTarget”)
