Leftos I edited MyCareer last night and played a couple of games with him. No crashing or anything but I did notice the split stats under Played Card were gone, Home and Away. I am 9 games into the career and if I recall from the last time I looked at them we were 4 home and 4 away. Also I was within the top 15 for assist in the league under league stats and now it says DNQ. (Does Not Qualify). It does not seem to affect all stats, just some of them, very odd.
Note: I don't think I am reporting a bug, just an observation
What I edited is, Lock Down Defender added, (it worked though I am a poor defender on this years game so I could barely tell the difference). And I changed his audio ID to match Clyde Drexler's. I do remember you stating the audio ID was just because of what JaoSming said about last years game. I am guessing that ID has more to do with stats than it does with audio.
I will revert back to my save before editing and replay the 2 games I played and let you know if my stats are still fubarred or not.
