@Daniel Salazar (zanqdo) Can you provide some more info? How did you create this file? The armature "RIG" has 867 bones, which is way too many for a developer to investigate.

@Sybren A. Stüvel (sybren) You're right I forgot a bunch of bones. I have re-uploaded the file!

This is one of my old Cosmos Laundromat rigs (Caterpillar)

Bone "spine_22" has a Copy Transform constraint that targets itself. This isn't valid, which is why you get the error message. Doesn't seem like a bug to me.
