Unable to marry?

@vintagesaturday Are you sure your Sim's NPC fiancé isn't an elder? Does he have gray or white hair and a slightly hunched back? Sims can't marry elders. I just lost weeks of progress building my Sims' relationships with their NPC significant others because they aged to elders today (adding insult to injury, I maxed out their relationships yesterday and was planning to marry them TODAY!). Apparently, this is not considered a bug, and Technical Support wouldn't help me. How are we supposed to know when NPC Sims are going to age up? There is no way to tell in the game!

I've lost my faith and trust in the developers and Tech Support. I spent real money on this game. I am quitting.
