To be frank, I am not planning to do an update on 'this' as it is working as expected , because the script has to work under all conditions including lagg & latency, it is slower than when you'd do it manually yourself.
I'm fairly certain you're starting the script, your character, and the butler incorrect. Please make sure that you start all three of those exactly as the thread states, all butler 'bug reports' are caused by people not starting it properly.
