I just ran into something new. It seems like what happens is all of the npcs in the area start walking around with their guns stuck to their hands. When this happens if I walk out of range of that area then walk back all of the new npcs are gone as if I never placed them. If I save and load they all appear again with their guns placed on their hands.

Anyone know the nature of what limit I just hit here?

You have to give us a little more information. Is this behavior happening due to a change you made in your own mod? Is it behavior you see when combining other people's mods? If it is your mod, are you using existing AI packages (which ones?) or new ones (what do they look like?) Does this happen with all your NPCS, only some, only ones in this particular room?

It happened after adding a considerable amount of civilian and mercenary guard npcs to Novac.
I'm not running any other mods other than what I am working on atm.

Probably just too many actors. Did you try increasing iAINumberActorsComplexScene ?
Just be warned that increasing that can have negative effects on gamestability.

kk ill just reduce the number of actors till it goes away.
Do creatures count for the same limit or do they have a different limit?

They count to the same.

I wonder why I never hit this limit with creatures alone then. Especially when testing my spawn script...
Did Martigen increase this for FO3 MMM?

hmm
