After the illithid brain has been defeated (one of the underdark quests in chapter 5), it is impossible to pick up the items, which are supposed to be the brain's blood and some gems. In another quest, either the brains blood or Koa-toan Prince blood is necessary, so the problem doesn't break that quest, but cuts out one of the alternatives.
