Hey Alex, love your bot!
I'm just having one major problem with it... the camera doesn't seem to want to adjust itself correctly to locate the furnace after withdrawing from the Lumbridge bank chest @ the combat academy. The camera will often be really high up looking down on my character after withdrawing and it'll just rest there. I think what's happening is that the bot is looking for the smelter (or the bank -- sometimes this issue comes up when standing at the furnace as well) but can't. The issue fixes itself if I manually move the camera down so that the furnace/chest comes into view, from that point the bot will be able to navigate to its objective and continue until it gets stuck again. This doesn't happen every time, but I'd say it's deifnitel yin the majority. I'd say, at best, it happens 4/10 times but it can easily happen every trip. The bot still works if you watch it, but unfortunately I am unable to leave the bot running while I afk.
Thanks for your work so far! You're making smelting a much less arduous task.
