Level update problem

[sssssssssss]

Ok, so Im not sure why this happens. On 2 levels out of all the rest of them, if update level or if uploading an update to the level, all the npc's disappear. very strange. the only npcs on the level are a playlooped and one to enableweapons, pause, and map. It also has a noplayerkilling on it too, even after enabling weapons. Every single time we update the level or upload an update, we have to /updatelevel gmapname on rc to fix it.
Any ideas?

Also cant pause. -_-
