Depth Charts

Why do they reset when you start an association? Is there any way to stop them from doing that?

only by controlling all 30 teams

Even when I control all teams, the depth charts don't start out how they are set before an association

then you can try opening the roster you used to start the association, copy and paste in the minutes assigned and roles and such in the players tab and the rotations in the teams tab into the association file.
