Rock the Vote Extend Map option broken

[getyadogsoffm]

So I got a RTV addon for my TTT server. Works fine except for one thing, whenever the option "Extend the Current Map" wins, no rounds are added to the current map and it continues with the map cycle. Here's the code I got for it(this is the unedited version I have)

RTV.VTab = {}
for i = 1, 9 do
	RTV.VTab["MAP_"..i] = 0
end
RTV.VTab["MAP_EXTEND"] = 0

RTV.Limit = math.Clamp( RTV.Limit, 2, 8 )

RTV.Maps = {}

RTV.TTT = false

RTV.TotalVotes = 0

RTV._ActualWait = CurTime() + RTV.Wait

local get = 0

local files, dirs = file.Find( "maps/*.bsp", "GAME" )

if RTV.UsePrefixes then
	for k, v in RandomPairs( files ) do
		if get >= RTV.Limit then 
			RTV.Maps[#RTV.Maps+1] = "Extend Current Map"
			break 
		end
		if string.gsub(v, ".bsp", "") == game.GetMap() then continue end
		for _, prefix in pairs( RTV.Prefixes ) do
			prefix = string.lower(prefix)
			if string.sub( string.lower(v), 0, #prefix ) == prefix then
				RTV.Maps[#RTV.Maps+1] = string.gsub( v, ".bsp", "" )
				get = get + 1
			end
		end
	end
end

SetGlobalBool( "In_Voting", false )

util.AddNetworkString( "RTVMaps" )

hook.Add( "Initialize", "Check for TTT gamemode", function()
	RTV.TTT = string.find( string.lower(gmod.GetGamemode().Name), "trouble in terror" )
end )

function RTV.ShouldChange()
	return RTV.TotalVotes >= math.Round(#player.GetAll()*0.66)
end

function RTV.RemoveVote()
	RTV.TotalVotes = math.Clamp( RTV.TotalVotes - 1, 0, math.huge )
end

function RTV.Start()

	SetGlobalBool( "In_Voting", true )

	for k, v in pairs( player.GetAll() ) do
		net.Start( "RTVMaps" )
			net.WriteTable( RTV.Maps )
		net.Send( v )
		umsg.Start( "RTVoting", v )
		umsg.End()
	end
	
	timer.Simple( 30, function()
		RTV.Finish()
	end )

end

function RTV.ChangeMap( map )

	if not map then return end

	if RTV.TTT then
