Short description of error
When I setup a Rig type for an Arm manually and then connect it to a palm rig type, the palm is not steadily connected to the arm.
When the Arm is created from Sample the problem does not occur.
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
Create a chain of 3 bones, give them limbs.arm rig type.
Create a limbs.super_plam from sample or manually and parent it to the hand.
Generate the rig.
Move the IK control in the generated rig. The palm floats around the hand bone in an unpredictable manner.
If limbs.arm is created from a sample this problem does not occur.
In the attached file I have a generated rig, created as described above:
Interestingly I am sure I have created arm+plam manually before without getting this error.
