Autoexec Disables Switching Modelviewer Environments

Using the autoexec code below seems to disable the environments slider, deleting it returns the original functionality, so I know it has something to do with this. Anyone know what code do I need to add in order to get this feature working again?

mount_vfs_liveries_path ("C:/Users/felix/Saved Games/DCS.openbeta/Liveries/")
mount_vfs_textures_path ("D:/DCS World OpenBeta/CoreMods/aircraft/FA-18C/Textures/FA-18C")

Maybe:

function scan_for_environment_cubes(path)
local lower_case = path:lower()	
for file in lfs.dir(path) do
	if not service_file(file) then
		local fn = path.."/"..file
		local attrMode = lfs.attributes(fn, "mode")
		if attrMode == "file" then
			local ext = string.sub(file,-4) 
			if '.dds' == ext then
				AddEnvironmentMap(file)
			end
		end
	end
end
end

I tried just appending it to my autoexec as is shown, and also replacing path with the actual filepath to my open beta folder but neither seemed to do the trick, any idea what I'm missing here?
