Hey, thanks for fixing errors in routes. I do find it troublesome to add some ways back into routes after heavily editing highway geometry, especially when I edit in Vespucci.

As for updating the routes, I have updated all trams, almost all 1xx, 3xx and A-N buses with their variants (except 125 and 150). I've also done that with the majority of 2xx lines and a few 9xx. So in the future if you're editing one of the lines I mentioned above, it's probably best if you only fix some errors such as missing segments, but the overall route should be correct.
You can always check which lines are changed on this website, marked by yellow outlines https://www.wroclaw.pl/komunikacja/rozklady-jazdy . Those routes should probably stay the way that they are without mapping the detour, unless you plan on reverting the change after the detour ends. If you have any questions related to routes and detours in Wrocław or any questions in general you can always send me a DM.
Take care!
