The formation thing is a conundrum. Many who miss this feature now also complained about its existance before.

But the fact is Sid is right, its not whether there's a penalty or not, its about conveying whether its a deliberate change or not, will be fixed or not......

And its not just about 1 or 2 penalty points.

There's also a slight issue I'm seeing where when I make I sub to a critical position, I lose possession until the Sub comes on - as if the departing player leaves the field immediately and the sub needs to wait (but that might just be me).
