1) Sometimes opens and closes the bank window and still thinks the bank window is open so the status says "Depositing" and the mouse is hovering over the steel bars but no bank window is open so it just gets stuck there.
2) Sometimes misclicks the steps and goes upstairs, add a failsafe to go back down.
3) Picks up random junk off the floor and doesn't drop it. I've had buckets, buckets of water, hammers, stamina pots(lol)
4) Sometimes only takes out 1 iron ore and thinks the inv is full and goes to make 1 steel bar
5) Sometimes clicks the bar dispenser before bars are made so the interface pops up and while the interface is up, bars cannot be made. Add a failsafe to close it if no bars please.
6) I start the bot with 1 inventory of coal loaded to make sure I don't make iron, however sometimes as soon as the bot adds the iron it turns into steel bars right away, or before the bot has a chance to put the coal on the belt. And then the bot just goes and banks the coal instead of putting it on the belt. Next time this happens = iron bars instead of steel. I always end up with 10-20% iron bars and 80-90% steel bars which is a bit annoying.
(set to make steel bars)
6 Is the most important.
