9 feet player dunking glitch

Hi everyone! I wonder if anyone can help me with my problem. I created a 9 feet tall player in my career mode in nba2k13 pc version. But every time I perform a slam dunk my player disapears and the game malfunctions all the players just runs around on the outside of the basketball court and the game is unplayable. I have to wait for the next quarter to start then I can play it again, the first couple of minutes the ball is invisible. I know it is posible because I have seen my 9 feet player perform a couple of slam dunks in the game during the season just that 97% of the time it mulfunctions. I tried it with 8.9, 8.8, 8.5, and 8.1 feet tall, the 8.1 feet tall I am able to dunk without a glitch maybe 78% of the time. I've tried maxing the dunk values to 255 in the cheat engine table but it does not help. I wonder if it is because my pc is outdated, but I have seen my 9 footer dunk in my 1st, 3rd, 4th game in the season. Can anyone please help me to fix this!? Thanks.

its an anti-cheat measure introduced last year or 2K11 (i forget) to prevent the online cheater problem. Only solution is to not have a player that tall.

Thanks Jaosming! I'm not ever planing to play a 9 feet tall player on line, because everyone would think I'm a cheater and a wimp. I wouldn't make a player like that for online, I make the 9 feet player for my personal nba2k13 league and for my personal enjoyment of the game. The makers of the nba2k games shouldn't put restriction like this because it should be by the players choices to play the game how ever they choose to. If the are concern about anyone cheating at that hieght, then they could always filter those out of the online league if they want. But they shouldn't completely take the option away for the customers that they have who doesn't play online much. I mean I just want to make my player like that for me personaly for the league that I created! Thank you very very much thouth Jaosming for trying to help me!!
