My addon causes people to crash :(

[Hackcraft]

This is the code I have been working on for a bit now. It's a crosshair designer. The problem is that when some people save a custom crosshair and then try to load it up again, their game crashes...

The loading is done through executing console commands to change a client convar's value. I have even added a timer to slow down the process but it hasn't helped.
--Snip of code, full code in pastebin

local function crossloadingsaves()

local crosshairloading = "crosshair_designer/save_" .. Hc_whichtoload .. ".txt"
if file.Exists( crosshairloading, "DATA" ) then
	local brokencrossstring = string.Explode( " ", file.Read( crosshairloading, "DATA" ) )

local hc_timer_i = 1

timer.Create( "hc_load_cross", 0.5, hc_con_num, function() 

RunConsoleCommand( hc_con_order[hc_timer_i], ( brokencrossstring[hc_timer_i] ) )
hc_timer_i = hc_timer_i + 1
	
	if hc_timer_i == hc_con_num then
		
	hc_timer_i = 1
	
	end
		
end)

else
file.Write( crosshairloading, "0 1 0 1 0 1 29 0 255 255 5 13 1 0 8 0 1 255 0 0 255" ) -- default config
RunConsoleCommand( "crosshairs_load_save" )
end

end
concommand.Add( "crosshairs_load_save", crossloadingsaves )
