Animation Rigging randomly twists joints


I am using the animation rigging system now that it’s out of preview. I am experimenting with walk cycles and this rig has worked completely fine up until this point. In the animation editor preview window, the skinned body parts no longer track to the targets, but this actually works fine in-game. What doesn’t work fine is the right-side hip, shoulder, and ankle (but not the knee and elbow) were twisted and seem to be completely uncontrollableto return to normal, with or without a hint target. They inherit the rotation the same way they did before that worked normally with the same animation earlier.

All animations now run through this twisted, messed up rig, even untouched ones that worked well previously. Any idea how to debug/correct this?

to future googlers, I never figured this out and rolled back my repo.
