After reading Henri200's post about having issues with more than one race session per weekend: http://isiforums.net/f/showthread.php/2214-Bug-with-XML-and-Num-Race-Sessions I decided to do some tests and here's my conclusion: At this moment (v1.005 build 49? ), only one qualification and max 2 race sessions per race weekend work. If more than 1 qualy and/or more than 2 race sessions, then some of drivers won't be able to enter those sessions, even if all of them have the same exact car (in my case, tests were done in Meganes).
