TTT Achievement Problem

[Safdo]

I already asked something about the achievement addon I recently bought and wanted to add an achievement which you get if you kill 2 traitors as an innocent with a H.U.G.E in one round. This thread was closed because I should ask the creater of the addon. The problem is: He doesn't respond to my messages. I tried to figure out myself how I can write this achievement and after a few tries I got this:

/* ──────────────────────────────────────────────────────────────────
	Kill 2TraitorInRound with Huge - 1
────────────────────────────────────────────────────────────────── */
local ACVMT = ACV_CreateACVStruct()
	ACVMT.LuaName = "ACV_TTT_MasterInnocent_Kill2TraitorHUGE"
	ACVMT.PrintName = "Dat Killabstauber"
	ACVMT.Description = "Töte 2 Traitor als Innocent mit einer H.U.G.E in einer Runde"
	ACVMT.Category = "Spezial"
	
	ACVMT.Order = 5
	ACVMT.Min = 0
	ACVMT.Max = 1
	
	function ACVMT:OnClear(ply)
	
		ply:PS_GivePoints(500)
		
	end

RegisterACVMT(ACVMT)

if SERVER then
	hook.Add("PlayerDeath","ACV " .. "PlayerDeath" .. ACVMT.LuaName,function( victim, infl, attacker, dmginfo )
		if victim:IsPlayer() and attacker:IsPlayer() then
			if victim:GetRole() == ROLE_TRAITOR and attacker:GetRole() == ROLE_INNOCENT then
				local wepName = getWepName(dmginfo)
				if wepName == weapon_zm_sledge then
					attacker.ACV_TraitorKillCountHUGE = attacker.ACV_TraitorKillCountHUGE or 0
					attacker.ACV_TraitorKillCountHUGE = attacker.ACV_TraitorKillCountHUGE + 1
					if attacker.ACV_TraitorKillCountHUGE == 2 then
						attacker:ACV_Increase(ACVMT.LuaName,1)
					end
				end
			end
		end
	end)
		hook.Add("TTTEndRound","ACV " .. "TTTEndRound" .. ACVMT.LuaName,function(type)
			for k,v in pairs(player.GetAll()) do
			v.ACV_TraitorKillCountHUGE = 0
			end
		end)
end

If I set this achievement and restart the server the achievement shows up in the achievement menu, but it doesn't work properly at all. The achievement ensures that if a traitor (only a traitor) dies, he is red marked (even without identification) on TAB and he can still speak with the living people even as a dead person. (without recognizeable error in the console)
I really want to get this kind of achievement, could someone help me fix that even without posting this to the autor himself?
