hi, i have a NPC in megaton, i have a travel package to travel to a xmarkerheading near the vault 108 entrance. There is a condition though, only if the stage of the quest is 10. When it is 10, he runs to the gate, goes through it and then runs to the location, though i have sleeped for 5 days solid and he still is not here, ois it coz the NPC has a long way to travel? or just me again lol

Maybe he dies.
However, there is a bug where NPCs when going through Megaton/Underworld gates disappear. For followers this is solved by waiting. I've had my NPCs clip through the ground and get stuck in Underworld so that may be your problem.
Try moving yourself to his location using console commands.

Need to check the "no low level processing" checkbox on him, and also he should be a persistant reference if he's not already.

What's happeneing is that without one or both of those things being enabled, he (his persistance) and/or his activity (his processing) is getting "suspended" once he leaves the players loaded 3D area. If you were to follow his path from Megaton to the vault, you'd at some point enter or load the cell where he went into limbo at (however far he made it to) and he'd magically reappear and be still on his way to the vault. Among other things, persistance helps keeps his body in the game world when you're not around, and keeping him in high level processing helps to ensure he doesn't forget what he should be doing when you're not around.

I had no idea that's what low level processing stood for (I havn't worked much with AI packages yet).

Thanks for the tips! :goodjob:

One for the notes :read:

It's an NPC setting that kinda puts their higher AI procedures "on hold" until the player HasLoaded3D == 1 for their location, then they wake up.
That's why you can hike across the wasteland and see a sentry bot and a radscorpion in the distance just kinda hanging out around each other, but as soon as you get close enough that you actually load the cell and the LOD pops in, they start fighting.
