This addon is basically the work of 
I have spend the last few days gonna over the original files making some changes fixes etc
I kept the name DS Houses, because its the name of the original work.

Changes include
Path LOD for most buildings, (AI Pathing)
Geo & Fire Geometry Fixes
Door Fixes

The addon is roughly only 180MB in size
To use the addon you just need to load it with CUPs.
Note: I will be pushing a new update later tonight with new serverkey. To fix issue with 2 floating buildings.
There is still some stuff left todo, but i will try keep the updates at most once a week.
