Tire and lap setting switch

Hi,

Last couple seasons a bug started....when ive set fueling proper in the morning and safe it, in much cases these settings change automatically. The laps drop with one or two and i didnt change it. Singapore previous season it dropped by 2 or 3 laps. Sometimes I had to change 2 times and the change was sometimes at both drivers at a differ time of the day. Its kinda annoying because couple times i found out to late.

With temperature change track evolves and so fuel used per lap changes this why it's recommend to do practice laps at similar weather as race. 

Hi Timo, in order for us to better identify what you're seeing, can you take screenshots of the problem when you see it in action? If you are able to record a video that works well too.
