Contract expiry bug

Hello, EA I have noticed that In every single one of my career mode saves whenever my player (with 6 months left) doesnt want to extend theire contract they sim until the 31st of December and then they tell me they dont want to extend theire contract and leave the club because "they arent getting enough games" and these things even though I keep at happy all the time, having played the most games and etc. and I dont even have the chance to sell them so I would like If this bug would be fixed or be done something with, and I assume that It happened to more people then just myself. Thanks
