The best place to start would be to put it in the professionbuddy thread, but if you would have read that, you would have noticed the bug has been reported....
Faced with the same problem, helped delete folders with the bot (previously stored folder settings and plugins) and download it again from the site. Translated by Google Translate.
I had the same problem a couple of days ago. I use a very simple PB profile that disenchants, mills, and prospects everything upon startup. It would say done with everything even though my bags were full of ghost iron ore. I did what dimkapir posted and it resolved the issue. I went into the bots folder and deleted the Professionbuddy folder. I then copied the Professionbuddy folder from another installation on my computer and pasted it in. It worked fine after that.
