Can you try this again and let me know if it happens. I just tested this out and had 0 problems with it. If it does it to you again, grab the information from the logger and let me know what it says.
Thanks!
Random events are triggered by the client, and you must enable them yourself. Has nothing to do with the script :p
Can you try this again and let me know what the logger said? If it isn't moving, then OSBot's walker isn't finding a position to walk to.
