If guide strands have been mirrored at some point and then I go on to create an asymmetrical style these automatically get mirrored when entering back to particle edit mode if x mirror is on in mesh edit mode
Exact steps for others to reproduce the error
Open file. You'll see and asymmetrical style in front view. Select object and go into Particle edit mode. Strands snap into a mirrored positions and style is lost.
It seems when x mirror is switched off in object edit mode this does not happen.
