Only one driver on track

Hello everyone
During the race I'm playing right now, I only have 1 driver on track (on a 2 cars league ofc).

I couldn't set up my 2nd driver's car or practice any lap with him, as a message of error appeared and the browser crashed.

Thank you guys for your help,

Try reselecting your drivers in the driver tab. This will most of the time fix the problem and you should be able to then do practice laps for both drivers.
Let us know if that works.

Well it looks like it worked... Thanks for the advice

No Problem Mickael, happy racing
