So I am having a problem with NPCs seeming to forget that they have a package and just stand around. I have created roughly 12 or so NPCs with incredibly drawn out packages that dictate basically every minute of every day. Each NPC has maybe 12 or so packages that obviously don't run at once, but allude the player that they are much more "real" than the stock NPCs. Now my .esp is 700kb, and just recently these NPCs just seem to forget what there doing and stand still as if they had no package currently running.

For comparison, I am currently running roughly 20 or so mods that range in size but mostly just insignificant plugins that don't change very much so my conclusion could be incorrect, but my next largest .esp is only 358kb and it is a realistic lighting mod. Do you think I am asking TOO much from the game?

It's the navmesh bug, see there : http://www.gamesas.com/topic/1345681-navmesh-bug/
