SSE NPC walking into walls, but Navemesh checks out

[LumenMystic]

I have added a new room onto an in game location and added navemesh. Everything checked out and no warnings were found. I also checked the paths around the corner into the room with green results. I finalized the navemesh and yet when the AI package sends an NPC into the room, they try to walk through the wall which has no navemesh in the gap, up to the wall or even close to the other side of the wall. Does anyone know what I might be missing?

Navmesh troubleshooting isn't my strong point, but the only things I could think of, offhand, would be to check and see if there is preferred pathing leftover; or possibly some other mod editing the same area, and they're trying to use its navmesh instead.

- If it's an interior vanilla cell, then check what thumbincubation said, It's the highest possibility.

- If it's an exterior cell then add a "NavCut Collision Box" around the cutted and lowered NavMesh vanilla piece, the NavMesh piece that has been edited.

Problem isn't completely fixed, but I've had NPCs at least go into the new room now. I'll keep going through my mods and removing any that change the same cell. Thanks for the help, I thought that the load order would override the navemesh changes so this took me by surprise.
