As mentioned before, it´s not the first time that happened. Another example:

At some point I was aware that I was not on the planned route because it could see the "white line" in the distance on the screen.
I have no idea why NN skipped that waypoint and I did notice too late. Audio announcement would be nice in that cases. I did check with G**gle maps, the originally planned road was not closed or had any other issues at that time.
