A couple of the keywords are different in SE I think. Like there is no BYOHHouseLocationType but there is a BYOHHouseLocationKeyword.
Also you have to add a doll idle inside the house (I don't think that's in the tutorial but I could of missed it).
I was getting the error: PHXCH - No SandboxOutside found!
Turned out my x marker with childsandboxoutside was just over the border of the cell. I moved it, which fixed the error.
Bless Home is now working and detecting 6 beds.
Thanks for the tutorial!
