Empty Enemy Camps

I did notice that there was some mention of a similar issue being fixed in the testlive 2.5 update;

Some people were switching in and out of ghost in admin mode to spawn npcs but I think they were mainly world/vault bosses…

I have an extremely limited knowledge when it comes to single player, so if @Croms_Faithful, or any other single player gurus know a work around, It would be appreciated.
