Lua NpcSystem ['Keyword_reply' missing... Skipping]

[Keram]

Yo wassup otlanders ;p

Well, while launching my console, those 2 errors show up at the end:

Warning NpcSystem
Parameter 'keyword_reply3' missing.Skipping...

and after that, the same one but different number after "reply".

Warning NpcSystem
Parameter 'keyword_reply4' missing.Skipping...

i searched in "notepad++" for this and here I found those lines in a modules.lua.svn-base file:

			if(i ~= 1) then
				local reply = NpcSystem.getParameter('keyword_reply' .. n)
				if(reply ~= nil) then
					self:addKeyword(keywords, reply)
				else
					print('[Warning] NpcSystem:', 'Parameter \'' .. 'keyword_reply' .. n .. '\' missing. Skipping...')
				end

Does any1 know why this is happening?
