The only things I can think of are that I have a conflict with the Morrowind Overhaul or I just don't know how to install mods correctly at all.
Both mods can in zip files with an esp. with a few meshes, textures, and sounds. I just extract to my Morrowind/Data Files/ right? Then I enable the mods in the Morrowind launcher by clicking Data Files and checking the mods to enable. I did all these steps and my Morrowind Overhaul works like a glove still, but the house mods still don't show up.
Please help. I am getting rather frustrated with this.
