The "Start Active Players" option is broken.
If a player selects "Start Active Players" it should start the optimum lineup, but it does not. The start % of the player should determine who is starting. My recent experience of Josh Smith starting at SS over Trea Turner is the final straw. In what universe is that the best choice? It is as if that function finds the worst possible lineup and goes with it, so long as active Pitchers are starting.
