The only way that I've been able to get the marriage capability back into the game has been to completely remove all of the Inteen mods that directly affect romantic relationships for teens and young adults as well as the multiple marriage functions. I've tried to contact the maker of the Inteen mods several times over the last couple of months to see if there might be any quick fix that could be done from the player end without him having to recode the mods, but so far there has been no response to my queries. They worked fine BEFORE the last game update, but not after. While the teen pregnancy and the Taboo aspects of these various mods continue to work, something that EA did to the game with that last update apparently conflicts with the mods. If anyone other than myself has noticed that since Sims 4 was upgraded to version 1.5.139.1020, your Sims have been unable to elope or plan a wedding, the problem is with the Inteen mods by Lostaccount which affect teens, teen/teen, teen/YA relationships and the polygamy functions.
