I actually tried playing CK2 with th DW mod in different situations. Using different characters of different genders, using and not using ruler designer, and using multiple bookmarked time periods. Not once did I see any of the buildings that you mentioned, that come from the DW mod, only the buildings from the base game were apparent.
I also failed to point out earlier, that i had MuteDay's Sexual Crusader mod, activated in some playthroughs and deactivated in others, while DW being activated. I also didn't notice any changes in the base game that would have been noticable while Sexual Crusader being activated.
