I think this is a case for the feedback section over at the official forum and not a bug.
It works fine, it's just really hard
Tried with me inviting someone, and it went much differently. Unlike when my sim was asked out, there was a list of goals in the top left.
The date ended well but seemed to bug near the end in a different way, with the two sims' actions being frozen (the rest of the sims in the apartment were fine), until I paused the game, after which the date ended, with a positive outcome.
I am not clear of your definitions though. "Something that needs tweeking' that is bloody annoying when it happens in that it tosses the relationship you have been working on for your sims out the window arbitrarily seems a lot more like a bug than a feedback issue. For future reference what would you classify as a bug?
Just an addendum. That last test was on Newcrest, with only the lot my sim family was living on built (so the date was at home). I'll try on WIllow Creek or Oasis and see what happens if I take a date to a social lot.
