Hair particle system moves position when loading I am using Blender 2.79b in cycles render trying to create a character model with realistic hair and eyebrows.  I have set up my hair using a vertex group for the scalp, and the eyebrows were placed using the add tool and X mirror.  Standard hair settings;


Hair dynamics unchecked
Velocity settings default
Rotation unchecked
Physics settings default
Render settings default with B-Spline at 6 steps
Display rendered with 6 steps
Children interpolated, display 25, render 25, long hair checked (unchecked for eyebrows)
Field weights default
Force field default
Vertex groups density set for scalp
Custom properties default
Textures default
Cycles hair settings with root at 0.20 and tip at 0 with close tip unchecked


After combing the hair into the position I want, I can render an image and it looks good.  I save the .blend file.  If I close the program and load the file I encounter a few problems.


The hair is now completely messed up and out of position.
Some of the hair parents have moved position, away from the vertex group in random places on the model, and sometimes floating in mid air away from the model.
The eyebrow I placed appears to stay in position, but the mirrored eyebrow is randomly scattered.


Any guidance would be greatly appreciated.
I believe I found the answer to my problems.  In my subdivision surface modifier I had view and render at different values.
