I'm also getting this error. I can't provide a screenshot, but the character is standing in front of the bank NPC, and the system message "There is no way." is popping up at the bottom.
EDIT: Not sure what happened, I changed nothing, but this problem has resolved itself. My advice to the guy above is to open and close your Tibia client entirely, or try a reboot, because that's all it could've been on my end.
EDIT 2: I recreated the problem. Bot starts correctly if you begin in the venore bank depot and it will make one full cycle through the hunting grounds without issue and go back and deposit gold. At that point, it does not deposit loot in the depot and heads toward the exit of the bank, attempts to use the equipped weapon, and then continually opens backpacks and browse field, closes backpacks, and repeats.
