Yeah we've known about these for years, there are a number of cases like this because they keep their dialogue despite the off chance that a Programmer could go through the caves and assimilate them, but there hasn't been a good way to change this behavior without a lot of work (it must be done manually for all potential instances in the scripts, to prevent a blanket fix from accidentally removing behavior that should be unchanged), so it remains for now. It's on my list to address at some point...
