For the past couple of weeks I have been working on a dungeon mod. Currently I’m no where near finished with it, but am at the point where I need to be setting the ambushes in places. However… they don’t work at all. The problem I’m having is that the ambush characters will appear or “sleep” where I place the marker. They are always a few feet away or standing on top of their coffin. When the triggers are activated lids blow off sarcophaguses and the NPCs come to life (moreso then they were). So the triggers do work.
Over this same period of time I have been reading and watching videos as to how they are set up. I have seen so many complaints on this same problem, but never a solution that works.
I have done everything from copy and past, to create from scratch. I have gone over ALL the packages, IA settings, triggers, markers, and navmesh. There isn’t a thing I haven’t left unchecked. I have even gone as far as unloading the mod, saving the game and reloading it.
Is there a bug / glitch causing this that I don't about?
I’m wondering if someone out there might know what is causing this and how I can fix it.
Any help at all will be welcomed and much appreciated.

Just an update here: It seems that I've encounter a whole new issue that's really getting on my nerves. First off, I get get the Draugr to stand where they should be. And I also got them to "sleep" prior to being activated. However, after setting everything up and testing it all I discovered that the only way to activate the ambushes are to shoot arrows, cast magic, or swing weapons around inside the trigger boxes. Simply running or walking into the trigger boxes will not activate the ambushes. I have set up all new trigger boxes, markers, and references and still have this problem. Would anyone have any ideas what is causing this?

There's a cell called WarehouseAmbushes. I don't know much about setting up ambushes myself, so I just use those. Sorry I can't be more help, but maybe you'll find something useful there.

Thanks for the reply. Yeah, I've been through the warehouse cells. I've copied a few of them and tried it as compaired to what I set up, and still the same thing. The ambushes only work if I swing a weapon around or fire arrows inside the trigger boxes. This is a really strange problem.
