But is it working when the bot has to use the "BROWSE FIELD"?
You can test it: change your looting settings to "Loot after all dead" (or simple move away from the body before looting it) then drop a gold coin on top of the body. The bot will try to "Browse field", and will fail to open the Thornback Tortoise body.
EDIT:
After testing it for a while, I saw that the bot has been able to loot some Thornbacks with Browse Field, but not all of them. It loots, let's say, 4 of 5 "easy" Tortoises (only one item/corpse above the Thornback to be opened, no other monster to be looted and no movement coming from targeting orders), but when it's a "hard" looting (other corpses around, other corpses to be looted in the same sqrm, presence of monster that requires movivement [like Reach & Circle]), the bot has a lot of problems and usually fail to loot almost all of this kind of body. With other monster, the bot would only fail to loot a small amount of "hard" corpses.
