Currently, when truce came, any attack that landed within the period are considered invalid.
However if you send attack within the truce period and land right after the end of the truce, the attack is still considered valid.
This brings huge disadvantages to the defender. As there is nothing you can do to try scouting others attack during truce period, while the attacker can safely send all the attack without being scouted.
Of course you can argue that you can also send attack to the opponent.
However it doesn't seem to be the idea of truce from administrator's perspective.
You're not supposed to gain any advantages with the introduction of truce. It's a period to give you peace.
Therefore I proposed to have an enhancement on the mechanics of truce.
Attack that sent during truce are also considered invalid, no matter the landing time is within truce or not.
This way the attacker cannot take any advantages from the truce. And defenders can do what they can as it is like the normal time.
The game will be more balance(or back to normal) with the introduction of such enhancement.
