I tried to get limpwurt roots from the hobgoblins in the dungeon south of Port Sarim, but no matter how many I kill, I don't get any drops! No bones, no limpwurt root, nothing! They are supposed to drop bones and limpwurts 100% of the time, along with other items sometimes. The Pirates there seem to drop things like normal, but there is definitely a problem with the Hobgoblins, even the level 42 one close to the ice area. None of them drop anything.
