One thing I noticed in this update D.4 is that the bot will not sell white items. Obviously it isn't intended to pick white items up but sometimes it happens if the bot clicks a 2nd time to pick up loot when the "Loot" timer is shorter and 2 pieces of loot are further apart than that run time. This used to be fine as it just vendored them next time it was there, but now this will slowly fill my inventory with white items, and I'd prefer not to have to increase the loot time to something stupid like 700.
You mentioned putting Hydra in the 4th slot, which I tried today, but I found that this made my character just run around randomly after/while looting, which slowed down the runs and missed loot. Not sure what exactly was the problem, but it didn't happen when I switched back to magic weapon.
A suggestion I have is getting the bot to place gems and tomes in tab1 of the stash every time, instead of opening tab 2 to put items in and also putting in tomes and gems then, which just causes extra clutter in the stash and wastes space.
