Mind. Blown. I was working with the wrong rigs the entire time. A wonderful person by the name of FlowerSimFactory created a proper IK rig for animators to work with and I feel entirely grateful! I can make animations and have them flow better than if I were animating everything one by one even though there was nothing wrong with the original rigs.
I'll still release the original 3 animations I made being that I've worked out the kinks with the XML file and have made sure everything works properly. I'd rather not let them go to waste.
I'll make animations with this these IK rigs going forward though ⌒°(❛ᴗ❛)°⌒
