i had a couple but can't remember off the top of my head except this one:
have a check implemented for player uniform numbers so when people are moved from A level and AA to say AAA you don't have 3 people with the same uniform number, similar to how you're not allowed to export without having exactly 25 players on your MLB squad. maybe make it so the uniform numbers that match turn red.
btw, i think your app was the single most important utility in the mvp series thus far. my mvp experience would not have been nearly as enjoyable with all these bugs had you not released MVPedit. thanks
