To be honest I don't know if it is a bug, but I investigate that you cannot use two command "Delay" is single module

Module.New('load', function(this)
if true then
this:Delay(2000, 5000)
ACTION
end
this:Delay(2000, 5000)
end)

First Delay won't work, but second will. As I said maybe it I on purpose and if it is, let me know ;)
