Christopher Fugitt at Civil3D Reminders pointed out to me that in this post where I created expressions to always draw a direction arrow downhill, I made my expressions too complicated. As a result my arrows would flip incorrectly at random openings of drawings. So by simplifying the 2 expressions to one expression:
IF({General Segment Grade}>0,3.14,0)
My problem disappeared. Thanks Christopher for being so helpful. I'm not a programmer but I love finding ways to speed up tasks or improve a workflow. I will share more of these as I find them.
On another note, please subscribe to this blog and PLEASE participate on the AUGI forums and the Autodesk Discussion Groups. They are the largest knowledge base you have access to and someone always has a better way.
Have a great day!
