Troop returning as no troops?
Funiest thing I have seen in a while.
It would be a good idea to have a note say "No reports have returned from the attack. You have to assume all the troops are dead."
No troop march back should be done. Lol!
As it is I have to wait the amount of time the ghost troops would have taken to arrive in order to free up that marching slot or move my town.
