The guy who was exploiting the bug earlier
http://igpmanager.com/play/?url=manager-profile/1748 (yes,he is changing his name,country etc. from time to time not to get kicked from the leagues) is joining the leagues where the season has not started yet,and of course it's suspicious. I'll keep an eye on his drivers' stats anyway during the season break,and I'm pretty sure they will improve and he'll leave the league before the 1st race :\
