Let leave training aside for a second (should have set the lineup if they were training and they shouldn't train only in the last game of the week either), but GS is the real issue here.
For the Nations who played in the time zones affected (Australia, Japan) you could have given some boost to all player's GS. GS caps at 9 but most players would be lower than that currently, so those who set perfect minutes would see GS improve a little while those who were screwed by not being able to set a lineup will see a larger improvement.
I think it's too late for this now though.
