[MWS] Exchange Vows Not Working
5 months ago
I was trying to have two sims get married but whenever I clicked on the option to get married using the arch it did nothing. I tried multiple times but the only that happened was the sim continuing to walk a bit more or was in a slightly different pose.
The button isn't grayed out or anything, it just does nothing. I did click on the sim my sim was marrying and the option to marry right then and there did work, so it's not just marriage in general.
