Route break when adding a new road

[Ne0Que]

Is it normal that a all routes break when i add a new piece of road to any piece of road that is used by any route? This is kinda anoying as i have to redo all the freaking routes over and over again when i just wanted to add a new piece of road. And then there is thing that makes it even more anoying: you have to remove all stops from the route if you make one mistake and add the stops that were put after the mistake again. Why isn't there just a select busstop feature and from there you add before or after this selected one a new stop?

Every new road built adjacent to a connection which is used by a line is a possible shortcut. So to take account for this, the route is interrupted on this particular part and then recalculated once the next vehicle arrives.
Just sit back, wait and enjoy the show instead of being annoyed and act untimely

To the second point: Once the route is finished (closed circle back to the depot), you can simply click on a stop and the game will automatically put it at the best position in the route, so that the way to and from this new station is the shortest in terms of where in the route this stop is played best.
Just try it and you will notice how it works (normally it works fine)
