OSRS Silence's Blast Furnace bot is messed up.

First of all, I am posting here because it won't show me the "Post New Thread" button on the Bot Support and Feedback page.
With that said,

Silence's Blast Furnace bot keeps logging out every now and then on OSRS while making runite bars and says "Out of Coal" when I have over 30k coal in bank and plenty of runite ore. MAKES NO SENSE! And yes im on a blast furnace world using a coal bag. Also yes I empty the coal bag before using the bot. And finally, yes that I have tried using the bot without coal bag and it still stops the bot and says the same thing on runemate client...
PLEASE HELP!
