If all of your players have remained at the same Game Shape level, I would be very suspicious of some kind of a bug. However, I cannot confirm this as I don't have the data from last week (from before training was run). We will have to wait and see what happens this training update and then can we draw some conclusions. At first glance, I cannot find any errors on the training code that could train everything else and ignore game shape. Let us know if it happens again (if the GS stays the same).
