wow, a feature line not showing still affects.
There is so much room for a 3rd party to do plan view ghosting of info a user would care about here.
You called it. I found a feature line that was used for utility location running right through this new feature line. The layer was turned off. So, it was suggested I put it on a different site, and this fixed that problem. The feature line still did not function properly as a breakline, though. I still got triangulation at one point.
