I created a mod that adds some buildings to Ivarstead and thus modifies the Ivarstead cell navmeshes to compensate for the building locations. I've gone through all the warnings, made sure the cells are connected, finalized, etc. However, every time I run out of town a few cells and run back, the NPCs seem to bug out. The Ivarstead cow ends up glitched in the wood mill, wild animals are running into walls, and so on. Any idea why this is happening? I've checked the navmeshes and they seem fine. We're allowed to edit exterior cell navmeshes right? Or does doing that bug everything out? I initially thought this was the navmesh bug (and it might be), but when I convert to ESM to try and fix it all the vanilla objects that I set to 'initially disabled' come back, like the Skyrim.esm is overwriting my mod's esm. I'm at my wit's end here
