So it is.
Even though the features "skip RP" and "offroad segment" behave similarly, they seem to be designed/implemented differently.
But what exactly does "skip" mean? It is not "ignore", because the RP is still part of the route. Obviously, only the calculation towards this point is not carried out, but it is simply connected by a direct line.
But there must be another aspect that prevents the last RP from being skipped.
