Many players encountered a problem during the raid. Players have the ability to repair the base and build during the raid. In this case, the player runs the risk of falling into a trap. It can be locked inside the base. The player can shut down the other player inside the base at the time of the raid. This is a bitter experience for the players.
Maybe better add buff “raid” for players who attack base and who protect base. When player begin raid, appear buff “raid”. The buff appears when the player uses against the building trebuchet, weapon, orbs or bombs. During this buff, player can not repair and to build the base. When the raid ceases, the buff disappears
