Where is the bot clicking? On the bank itself? Inside the bank, as in it's attempting to walk into the bank? With the bank interface open unable to withdraw anything?
Edit: Judging by the log I am assuming the bot is attempting to walk into the bank, and failing to do so. If that's the case, it looks like a web walking problem. Please let me know ASAP if that is what the bot is doing. I will have to write a temporary work around and report the issue to OSBot devs if this does look to be an issue with web walking.
Also, is it close to or far from the bank? Is it clicking on a tile in the bank, or on the minimap?
