Avoiding a big thunderstorm? ;-)
But seriously, a lot of the routings shown are wrong, for numerous reasons, including operators often changing codes, charter flights being sometimes very random and RadarBox using a previous charter route's code, and sometimes crew entering them wrong.
We don't have a live link to flight plans like sites like Flightaware have (for some parts of the world), and until we do, we're often going to find that the routes shown in RadarBox are wrong.
There are many threads on the forum discussing this in more depth.
