I'm using MCA 1.12.2, and for some weird reason, there is no kiss, hug, or flirt option for any of my villagers except for one, and all of them are adults.

Also, when I try to give an unmarried villager with 5 gold hearts an engagement ring, it says they don't know what it is or why I'm giving it to them.

Are you using any other mods alongside MCA?

Found a potential issue. 64342a9 should help when the update is released.
