Another member brought up he was having trouble with bot picking up items on shoutbox. Ash and I were trying to help him, had trouble understanding what completely was wrong (language barrier). Anyways, he had a valid issue.
I watched bot for a while tonight. At a large amount of items on ground, bot scanned up and then down and then started about 1-2 seconds of the circular pattern it usually would do, and then went back to the up and down motion in an infinite loop. What I have been used to seeing is that bot scans up, then down, then a circular motion with wider arc as it progressed. This is not happening anymore causing a continuous loop to occur.
So, I don't know if this was intentional or a bug.
PS - I don't have highlight items on, I do have use alt for pickup, I am using Win 7 with aero theme. There, got that out of the way.
