AttributeError when using remote

[fgolemo]

Hey I'm using the Poppy remotely and randomly every once in a while I get this error (but nothing bad seems to happen otherwise):

poppy@flogo4:~/ $ poppy-services --remote poppy-ergo-jr                                                                                           
Attempt 1 to start the robot...        
Robot created and running!

    return attrgetter('{}.{}'.format(object, register))(self.robot)           
AttributeError: 'DxlXL320Motor' object has no attribute 'safe_compliant'

Any ideas how to fix this, or what's causing this?
