Statistics/History for received troops

I would like to have a history board for received troops because i think a lot of players know the problem of getting wrong troops, especially in clan war.

You request a golem to attack, go offline for some minutes and when you come back you have some Barbs or Archers or worse. Since you have only 30 slots no golem fits in and the guy that wanted to give you one couldn't spend and is now offline.

We want to punish those guys but you only see who gave you troops when you are online in that moment.

If we could look in a "received troops in the past" board, we could punish those guys and probably it will decrease the amount of wrong troops spent because everyone knows that he could be punished for it.
