Gameplay - players could get disconnected during a Showdown race - 3900047

When trying to start a Showdown race (all classes of cars are able to enter, but slower classes start earlier than faster classes) in a convoy, the race will not start. Everything seems normal until the list of players/cars appears, this screen is shown for much longer than usual (about a minute). After that, all players in the convoy get a notification that they are disconnected, and are sent back to online freeroam.
Races without the Showdown class selection work without any problems. All other online parts of the game are fine too, and all the players in the convoy have a good internet connection. The problem happens with multiple different convoy leaders, and on different tracks.

@SmaugiaVolans is this issue still happening since the most recent game update?
