So after following everything, reading through the comments, starting a new game, and triple checking and running through the list, the spell still says the house isn't suitable. Ran a log and couldn't find reference to the mod. I made sure all the external stuff was in the the same cell as the home. So I'm quite unsure. I have the house cell set to player faction for ownership. Also, when I cast the spell outside, it says this isn't one of my homes.
Here is my log:Spoiler
There's a ton of errors regarding missing files in that log. Skyrim is looking for the individual Unofficial Patches when USLEEP has been installed. Surely that has something to do with it. Also, the Bless Home spell is cast inside the home. The exterior cell only serves as the location so the kids "know" where to go.
Okay. I thought that usleep was all the patches in one! Okay, I'll get the individuals along with usleep. Currently reinstalling cold and starting over.
NO NO NO Brotha!, USLEEP replaces all the individual patches. That's all ya need.
So how do I get Skyrim to see USLEEP instead of trying to find each individual patch? We'll see how when this reinstall is done.
