I had created a test mod the first day the creation kit came out, made a cell and placed an NPC in it, and the NPC appeared fine, exactly where I put him in the CK.
But now none of the actors in any of my mods spawn, even the first mod I made, which had worked fine.
Either they spawn somewhere other than where I put them, or them don't seem to spawn at all.
And in one instance, all the actors in the cell died when I entered.
Anyone know what I might be causing this?
