can someone help me! French league

Hello I've played fm for years and normally get it on the day of release but I fell out of love with fm10 but after a short break of 4 months from the game im ready to go again so im telling the wife to get it me for christmas but I've read some slightly worrying comments about bugs on the forum. I only play in France because im an avid French football fan but I read something the other day about squad numbers getting messed up in Germany and France because of registering B teams can anyone confirm to me if this is true I know its not game breaking but annoying and if there's any other bugs for the French leagues that people know about what will either be annoying or game breaking and will give me second thoughts about the purchase. I would be grateful for any help.Thanks le crab.

I play with PSG and I haven't encountered any bugs at all.
