Well spotted Bill.
It's generic, all the cars I have tried at a few different tracks are the same off line.
There may be a combo that works but I doubt it, and I don't have time to go through all
possible combinations.
There is a server setting "Use fixed setup" that does this effect, but we (as far as I know) have
never used it? Anyway. I have started our server with this week's race details, and I have
made sure that "used fixed setup" is off, and if you go online you can save and load setups as normal.
My best guess is that you have found a "feature" Bill, where off line now is set to "use fixed setup"
and should not be.
I expect it has already been reported, unless it is just us?
