Just remember to but the wall and/or obstructions in the same place when making your edits.
There is another model file somewhere that has that info.
*:\Conquer 2.0\map\map\house01.DMap & house03.DMap
*:\Conquer 2.0\map\puzzle\house01.pul & house03.pul
*:\Conquer 2.0\map\Scene\house13.scene -> house24.scene
*:\Conquer 2.0\ani\family.ani
If you can figure out what those do, let us know.
