I see nothing strange in that. If I disco while using WEP, in my opinion it could be quite normal that the WEP will be used during the relogging time. Especially if I reboot the computer. After all, the game doesn't stop around the discoed plane, and the plane continues its travel with the same speed and direction. You can try this with WEP and autopilot. If you wish, you can even clock the time used to log into the game and then see how far you get with WEP in that time using autopilot. Also take into account that you may have used the WEP some already before the disco. Just my thoughts, not to be taken offensively.
