After having some errors sorted out, everything turned out to work right...well, sort of.
I decided that my character was in need of a house to store his stuff in. Go I went to Leyawiin, to have a chat the count, only that he (like many other NPCs) doesn't want to talk to me about current rumors and really isn't going to let me buy that "house". Turns out their disposition towards me seems to be fixed stuck at 0.00, and any attempts to remedy that, either by console or by trying to "persuade" them, just fails miserably.
Now, this is probably something I've messed up in the load order or in the bashed patch. Usually I tend to be able to solve any problems on my own, but not this time.
I've searched the forum, but nothing has showed up. Unless I used the wrong keywords, that is.
In short: some NPCs has a disposition of 0, no matter what I do. Unless I sell them some high priced items, although I'm not really sure on that yet.
Oh, and my load order would be pretty useful, too. (There's still some things left to update or change...'tis on my to-do list.)
