I did a realignment this past fall and have since learned that the section of centerline ended up generating a monotonic route. I've called support and what they talked me through doing hasn't helped. I'm about to just nuke the route and draw again... but I'm afraid it'll happen still. I've tried recreating the centerline in that spot, but that didn't work either. Tried Generating Routes again, and that didn't work. I'm out of ideas and really need to get this solved/fixed asap.
