Just want to be sure: UESP says that wardrobes are always safe. So does that mean a guy who robs my house can't steal from a wardrobe? Because if so, it's time to store all my stuff in my new Whiterun house...
Also, how do you upgrade your houses? Someone said mods before i think, which I'm not sure I believe now since UESP lists prices for fully upgrading them. But that guy in the bathrobe in Dragonsreach doesn't give me options to so...
Edit: Yes, he started offering the option.
