Training

I think we shoul be able to train the drivers after the race, not after 24h.
For example in I train him at 10pm and the race is at 1am, I don't want to wait 21 h.

Robert, what you are experiencing is an elaborate way to stop people from training their drivers any more than once per race

But I thought preventing them from training til after the next race would do that. I makes if really difficult. 

That was the problem Ken. You could join 10 different leagues in one day if you wanted too, and train your drivers 10 times in one day. Hence, a 24 hour window was put in place.

It's actually a 22-hour window as Jason said, but yes, that was the problem.
