Blank screen after date with Vladimir (sugar daddy, not step daddy).
Game ver 0.8.9.2., no mods. Changed main home to city house before date.
Edit:
Dropoff after his dates worked before, but was always a litlle messy.
First 2 dates (main res was univ dorm): dropoff was Pavlovsk, apt house stairwell. Annoying, but only takes a train ticket to fix. At least Misha didn't see my cum covered ass.
Next 10 or so dates (same main res): dropoff was dorm elevator (the "take elevator" or" go out" question). Oooookay, nearly were I'm supposed to be post sex.
Then came the main res change to city house (see above).
