If the script post/page doesnt have mentioned Force Refill then it does not have it.
It still is 100% afk script, just increase the minimum amount of potions to leave to avoid running out.
You will be notified when the updated version comes out.
Edit: @selassie Redownload script and try v1.3.1, unfortunately I was unable to intensively test the Force Refill due to lack time but anything just let me know.
