Firstly; #1 is clearly mentioned on the bot page that you empty the coal bag before starting, as the bot has no idea how much coal you have in the bag when it starts. I'll look into alternative measures to stop it crashing on start as that is definitely not intentional but you should not start the bot with coalbag already full
Secondly; If the bot is not taking stuff out of the dispenser then you have stuff already in the blast furnace which hasn't been cleansed out, the bot can detect that "Something" is in there, so it will close and re-open the UI thinking that the furnace will drop more bars in.
Finally the miss clicks I am investigating as I had believed I had resolved this but if this still remains I will re-investigate.
Please ensure that your blast furnace doesn't have any thing in it already, you can test that the taking bars works by just running the lite version with bronze bars and making sure that does the full flow without costing you any money.
I greately apologize. I didn't realize you had updated the overview page. Thanks for getting back to me! I'll give it another go!
