Ok just tested it out.
1,3k bars per hour which is awesome.
But there is a huge problem in the code i think you should realyl fix it because people will get banned just because of that it makes you look like a bot 101%.
Here is the problem if you make mithril or adamant bars ( didnt test rune).
You start the script. It pick out coal, fills the bag, fill the inventory and runs to the convoy belt and fills it. Everything fine and smooth.
Then it does back to bank pick out COAL again fills the bag and pick out Mithril.
Runs to the convoy deposits mithril and then coal which is ok i guess. But here comes the problem:
Then it takes the bars banks them and takes out coal fills bag takes coal it repeats itself. BUT
When it comes to the belt it loads the inventory coal. Emptys the bag AND fills the bag again. Somehow because it deposits coal when it brings mithril the bot
detects its enoguh coal in the fournace and it doesnt deposit anymore. So it just emptys it trys to deposit and click fill again and runs to take mithril.
Tl;dr
Change the code that it doesnt fill the coal bag when the mithril ore run is going.
