Okay, the mechanic of the Professional Scouts is very great but i think there is a problem with it.
Recently in my game i was playing with my friends 4v4 (in min 48) enemy team destroyed my wall, that is okay, when i try to repair or re-build the wall, i couldn’t. Because the deer were moved to the wall that collapsed by enemy scouts 
So in that minute i couldn’t move it. Because there is no time for get upgrade Professional Scouts and make new scouts for move deer carcass.
I think game has to an update for that. I mean i am not telling to remove Professional Scouts, just telling to we should able to make make structures on it.
