Pipe Network Line Style Keeps Automatically Matching the Current Linestyle

How do I get the line style of my pipe networks to stop

matching the line style of the current layer I am working on?

This has been happening ever since I switched to AutoCAD Civil

3D 2014.

In a nutshell: My storm pipe networks are always drawn in

solid white lines. However, if I do some editing on another

layer in the drawing -- say existing gas which looks like

-------- GAS ------- GAS ------- GAS -------, then the lines

for my pipe network will look and print as existing gas. If I

change to a waterline layer, then my pipe network will look

and print like the waterline layer.

Also, the change seems to be superficial -- the line style as

it is listed in the properties of the pipe network still shows

as a solid white line even though it doesn't look not print as

a solid white line while another layer is the current layer.

How can I make this stop before I go bezerk!

I've never seen that before.

A couple of things to try/look at:

Have you restarted?

Is this only in one file, some files, or all files?

Yes, I've tried restarting. And it happens in all my files -- including new files.
