On some occasions, seemingly at random, when we organize multiplayer races, some players experience issues with loading their car setup. It appears to be loaded correctly, and the parameters in the setup menu match the intended values. However, once on track, the car seems to behave according to the default parameters. For instance, we’ve encountered this issue multiple times at Daytona, where some of us hit the rev limiter well before the finish line and experienced unstable car behavior — something that does not happen when the setup loads correctly.
If you use the reset to pits option, just open you setup (advanced) before you go to track again (even there is change of session in between) as a workaround for that bug. If I do that, it never happens to me.
