Issue #29331: Goldenglow Estate Basement navmesh 000b48c5
The main navmesh 000b48c5 has the 2 doors. There are 2 disconnected islands, but the small one is already on top of the ceiling. The larger one has the last NPC in it, and s/he's stuck. Followers run back and forth trying to follow down the hallway. There's an obvious hole.
Connecting them causes a dreaded navmesh deletion, so I've used SSEEdit (copy with overwriting) followed by CK2 (deleting the excess triangles) to make a 1 triangle replacement for the deleted 0002beed, also just above the ceiling near the other island. I'll have to write-up the process.
