Im on PS4, so I wouldnt be able to DL the roster. But I do remember a few years back, a issue with NBA2k and bug which would cause duplicate players now I think of it. Cant remember what cause it, I just remember taking a 2k roster file, and back dating it to Opening night, and I ended up with duplicates. So it looks like that bug is back this yr.
Need to report it to the devs, but they didnt fix it a few years ago, so I wouldnt count on it being fixed now either, but who knows maybe they will be able to patch it in and fix it.
I suppose ever dog has its day, so Lonzo Ball, having a game where he actually makes a a few 3's I suppose is possible, even IRL
So unless its happening all the time, I wouldnt worry to much about that.
