Occasionally it will get a new invent but not interact with the portable forge, and instead just hovers the mouse on it (I have the special cursors or whatever on, so I can see it change to the anvil icon) If I pause it and manually open the forge menu it will resume properly when I unpause, but can potentially get stuck again. Because the bot is still trying to interact with the forge - still moves the mouse around, etc - it will not log from inactivity. I let it sit like this for probably close to 10 mins and it didn't work itself out.
See attached for the log.
