Dating causes glitches

When trying to "create date" or "ask on date" interaction foes through and romance is shown to increase, but screen does not pop up to either create the date or choose a date location. I had to use the phone to have my sim ask the other sim in my household on a date. Once on the date, interactions worked fine for a couple of minutes. Then, all of a sudden double qued interactions would stop working. Sims would get half way through the first interaction, then reset. Relationship is shown to increase, yet the action is never carried through. I ended the date and brought them home. I tried romantic interactions again and that did not work. Then, I attempted to have my sims woohoo. The sims ask the question, do their giddy dance, but then glitch out. Again, the sims are shown to increase relationship. I exited the game save to the main menu without saving, and went back into the game. Romantic interactions still do not work. Romantic interactions as teens work and so do dates. But, once their aged up to young adults and go on a date, the sims continue glitching.
