I saw this in the code:
PHP Code:
c_RemovalType = CreateConVar("sm_ag_removaltype", "0", "0 - Disabled. 1 - Removes godmode when an attack key is pressed. 2 - Removes godmode when a player hurts a player. 3 - Removes godmode when a player killed a player.");
Does the plugin work fine until the player fires their weapon, like a rocket jump? If so, try setting sm_ag_removaltype to 0
