Now a few questions, I heard in the lore that a few Stewerds are untrustworthy. I had the Housecarl from Falkreath be my Steward and she's completely vanished, like nowhere. So is she on the list of "untrustworthy Stewards?

Also, I am on XBox 360 right now and plan to use Morthal as my actual house (wife, kids, etc etc).

Any tips and tricks. Cause like I said I want to know if some Stewards like Reyya might not be the best choice.....

Have never had any problems with any of them, you might however want to not use the houscarl as steward if you want more people. Use another follower as stevard and the housecarl as an extra guard.

Note that they move around a bit being either inside or outside around the area.
