As stated in the 2.29 Hotfix, the optional objective is still spawning incorrectly on Derailed. Just thought it would be pertinent to the developers to see a screenshot of this. I apologize that the screenshot doesn’t show where on the map exactly it is, but it is just outside of the trainyard if that is any indication of where it is.
As one can see in the image, it is spawning 76 meters below the desired position. Perhaps this is just a y-coordinate issue that could be resolved. I do not know precisely how the positions are defined in the game, but it might be a simple fix. Hopefully this helps you devs out.
