BLITZ TOURNAMENT

I'm talking about swapping troops. Let me explain. I took one unit of each, placed mine, and transferred them to the ally's empty slots. That's it. Nothing more can be done with the ally. Their unit icons are inactive. They only light up when I select the same unit. Meaning, I can replenish, but I cannot take or replace.

I have The Shadow of Death 3.0 and it works there — which means they fixed it, out of stupidity :) It used to be a feature :)
But why isn't anything written in the doc about this being patched? Now it will be considered a bug. But actually, then why leave that exchange window with the ally at all, and even leave the ability to give troops only one way? In the unpatched version, even this feature worked better :) Maybe this became a bug after the patch :)
