I'm trying to host a wedding event for my newly engaged sims, however whatever event I do, whether it's an engagement party or the actual wedding, my sims partner never turns up. I even try to invite them via phone, but they don't turn up. The only way around it is to go to the wedding venue beforehand and set up the wedding there while your sims partner is there. Can anyone fix this? It's quite annoying.
