[Gameplay] Sometimes the attack command doesn't overwrite the move command

It happens very rarely but since i attack move attack a lot of times this increases the chance of it happening.

What it happens: I click somewhere to move. I attack command something. My champion moves to the place i pointed it to move. Waits a few seconds, then goes to attack the target. Expected: I click somewhere to move. I attack command something. My champion moves towards the place i pointed it to move but stops the moment i do an attack command and does the attack command.
