The zone isn't done yet, however the part you're on works fine. I've done it a million times in testing. The only thing I can think of is if multiple NPCs are killed at the exact same time they won't be counted (the count is done as each are killed, not at the end) I was planning on lowering the counts required for each phase to get around this by a couple. Though, in this particular case it wouldn't be difficult to have the untargetables probe to see which are up, if none are then spawn the normal versions. I'll change that when I get back to finishing the zone. There is still a lot of tweaking I have left to do.
