Hierarchy sine angle mirror bug

[WilsonPercival]

Problem description

I have two sprites connected by a hierarchy. The child sprite has a Sine behavior with the Movement parameter set to Angle and the Magnitude parameter set to 0. When I mirror the parent, the child sprite is rotated to a random angle.
