This is the log and one of the swap files I use:
https://ufile.io/f/dpwyz
There are two mods that are not working and both have included LOD files:
Simplicity of Settlements - Dragon Bridge - Base Object Swapper
Unique Towns - Base Object Swapper
With Unique Towns, the mod includes an alternative to BOS to swap the houses using a plugin, running Dyndolod with that plugin will generate the LOD correctly, but with only the SWAP file, the LOD doesn't change.
