problems with lua AddSingleFile - downloads to wrong path

[zassadgh2]

Hello, this baffels me, I have this script:

local models = {
	'astronauthelmet',
	'cakehat',
	'duncehat',
	'gmod_tower',
	'sam',
	'santa',
	'vikinghelmet',
	'thresh'
}

local materials = {
	'models/astronauthelmet',
	'models/cakehat',
	'models/duncehat',
	'models/gmod_tower',
	'models/sam',
	'models/santa',
	'models/vikinghelmet',
	'models/thresh'
}

-- end

function resource.AddDir(dir)
	local f, d = file.Find(dir .. '/*', 'GAME')
	
	for k, v in pairs(f) do
		resource.AddSingleFile(dir .. '/' .. v)
	end
	
	for k, v in pairs(d) do
		resource.AddDir(dir .. '/' .. v)
	end
end

for _, mf in pairs(models) do
	resource.AddDir('models/' .. mf)
end

for _, mf in pairs(materials) do
	resource.AddDir('materials/' .. mf)
end

it should download all of the above to garrysmod/models(garrysmod/download/models) and garrysmod/materials(garrysmod/download/materials), but it downloads all the files to garrysmod\download\addons\accessoriespack and even fails to download to garrysmod\download\addons\playermodels?
Here is the full addon(simply pointshop with a few modifications) as a zip: [url]http://speedy.sh/AEtZ7/pointshop.zip[/url]

Normally I don't have problems with simple lua, but in this case I simply can't figure it out, it should work - everything.
