GK catches the ball, then back up until he concedes a corner

Hi I have this problem with the GK claims the cross ball, then he takes a ouple of small steps backwards until he concedes a corner against my team. Does this happen to other people, or is it only my GK who`s shit? I can remember this was a problem on older versions of FM, but if I remember correctly they managed to remove it form FM13.

Is it a bug?

I've seen it happen a couple of times on FM but to be fair it does happen in real life too if they lose their balance. It does happen perhaps a little too much in fm but the always-improving match engine will be cutting down on these little errors every year
