Because its in the same position as the "training button" in the training building. Or put a confirmation message after clicking the auto "assign button".
Several times I click the training button to enter the training page and the system recognizes a double tap (and I dont have Parkinson), I dont even see the training page and I get the message "congratulation, several players raise a level - or something like that" (I acumulate a lot of training player points to make the placing choice only once)

Thanks from Malequio RxCx.

I understand the problem. will try to add a delay before enabling the button, or a confirm dialog.
