I get it too.
This usually happens when the bot tries to right click -> put ore on conveyor belt, but then it misclicks the "put ore on conveyor belt" by a pixel and then walks to another location. Happens about 25% of the time whenever it runs to put ore on conveyor belt.
I don't know how I can screenshot the bot doing this Khaleesi, I hope I described it well enough.
I have used this script for 2 days and a few times this bot is stuck and won't do anything.
Here is the logger, let me know if you need more information or anything
