Just a quick question regarding some NPC's I have placed in an altered exterior space (nav mesh is complete and I have triple checked for errors). The NPC's re-locate to the nearest nav mesh that was originally done by Bethesda (as in it looks as though they do not wish to stand on my created nav mesh). Is this a nav mesh bug? Both with and without packages they do this, and I might add I have done several mods with NPC's and I haven't done anything differently, yet it's the first time they do this. On interior cells they are fine.

I just want to know if its worth spending more hours on this if its a nav mesh bug? Any ideas or has someone encountered this before?

are you using an esm or esp

esp

well, navmeshes on esps will break on 2nd load (initial load will usually work fine, but if you leave the area and return, the navmesh will break, leaving the NPC looking for a functional navmesh, or just stand there doing nothing, or disappear completely). this is the navmesh bug.

esms can circumvent this to some degree, but if you are editing vanilla navmeshes, the esm will also break (the esm workaround is only effective if you are creating completely new navmeshes and not editing any vanilla)

Ok thanks heaps! I thought it might have been the case, I just hadn't encountered the nav mesh bug to this degree yet. Most likely because of the higher number of NPC's I'm creating correlating to a greater number of potential errors haha. Thanks again!
