I've tried to run the bot in the area doing Black Alumen and it mines one point fine and then the bot runs backwards into a wall in a random direction and then gets stuck.
The only time my bot ever walks oddly like that is if I'm in gamepad mode. Its fairly inconsistent in this performance, I can gather bot in gamepad mode for sometimes 20-30 minutes with no problem, and then suddenly it wants to start walking odd and other times as soon as it starts its running backwards sideways and every which way but where its supposed to go.
However per the configuration directions, it only farms in mouse mode so if the bot starts walking sideways or running backwards, switch the control mode under Character Configuration, possibly stop & start the bot gathering again.
