[Inverse Kinematics] EndEffector must be a descendant of ChainRoot

[davness]

Starting around (i.e. no earlier than) from 7:20PM GMT (12:20PM PST) today, I started receiving the following warnings on my game:

EndEffector must be a descendant of ChainRoot

For context, the IKControls used in my project are, and always have been set up like this and haven’t changed recently:

> <root>.Humanoid.IKLeftArm
  ChainRoot: <root>.LeftUpperArm.LeftShoulderRigAttachment
EndEffector: <root>.LeftHand

> <root>.Humanoid.IKLeftLeg
  ChainRoot: <root>.LeftUpperLeg
EndEffector: <root>.LeftFoot

> <root>.Humanoid.IKRightArm
  ChainRoot: <root>.RightUpperArm.RightShoulderRigAttachment.Attachment <- this attachment is added in after the avatar is loaded
EndEffector: <root>.RightHand

> <root>.Humanoid.IKRightLeg
  ChainRoot: <root>.RightUpperLeg
EndEffector: <root>.RightFoot

Where <root> is a R15 avatar. (Though similar warnings appear for the R6 counterparts as well)

Naturally, EndEffector is, in fact, not a descendant of ChainRoot, but it has always worked well this way. Is this a new thing or a bug?

I’ve also started receiving these warnings.

Game gives the warning even when the EndEffector is a descendant of ChainRoot.

Hi all, thank you for reporting this and providing repro instructions. We’ve rolled back the check (you should no longer see the warning) and currently looking into the issue.
