So, I am using the latest Basecamp (4.8.6), the latest Garmin Thailand map (CN Thailand NT 2019.40 [Dual]), and the most recent Nightrider update (2019-11-14) and I have noticed something curious. With some (though not all) of the shaping/waypoints, if I set them on one map, they are slightly off on the other. They are off enough to actually make the line look like it is off the road. If I reset them on the second map, the road corrects its path but when I go back to the other map, the point is off there and in a different place than I put it originally. I have used the maps loaded on my Garmin and also loaded on a USB with the same results. I'm not sure which map is off. I have attached 2 screenshots to show you what I mean. The first is a point set on the Garmin map and the second is the same point after shifting to the OSM map.
Am I the only one that is seeing this? I haven't had a chance to go out and try time on a route yet to see if it is going to work or not but Will update when I do.
