I've been having the exact same issue ever since I downloaded DD again recently. (Last time I had the ability to play, WP and KW were still in effect separately.) I have a lot of mods downloaded, so I'm gonna have to go through and troubleshoot with having just DD downloaded and necessary mods, to see if it's an issue of conflicting mods.
I get lot traits, and traits for people, they're still available, but p much all ability to interact hasn't worked thus far, and no DD icon or related option pops up anywhere. :T
