Corner instructions ignored.

My corner instructions for my ultra defensive (last few minutes holding onto a lead) tactic keep being ignored.

Just had one where my players are:

Corner taker.

Strong Striker set to "come short".

4 players outside the penalty box, and 3 marking the 2 opposition forwards.

There is no-one in the box apart from their keeper and 4 defenders (which seems a bit silly).

Instructions are set to "Short", time wasting to often. Creative freedom is minimal.

He goes and kicks it into the box where no-one is :nono: they get the ball and can launch an attack. They don't score, but it's 1 minute left, the striker should be standing right with the taker and holding it there.
