What did you try to do?
I checked the lap records of each circuit to update my personal spreadsheet.
What happened instead?
I found that a total of 22 qualifying lap records and 2 race lap records were broken on June 23. These times are often 1 to 4 seconds quicker than what can be normally achieved. See my spreadsheet for the details. I suspect this is related to the bugs (see this forum thread) caused by the simulator update on June 23.

PC
What operating system is your PC?

Which browser did you experience the problem in?

Can the bug be reproduced?
