Describe the bug:
Me and a few friends are playing with the MCA mod installed, but after the recent updates we've been unable to use the player-interaction feature of the mod. We're unable to open up the marriage menu.

We can still interact with NPCs just fine, and other parts of the mod seems to be working normally.
I'm not 100% caught up with the mod, so I don't know if this is an intended feature or a glitch from my end, but the crystal ball (amongst a few other items) are missing since the update, and none of the NPCs have any profession interaction option anymore.

We also tried using different versions of forge (all under 1.12.2) but that didn't work.

Steps to Reproduce:

• Launch Minecraft
• Create a World
• Open to LAN
• Have someone join
• Try to interact with a player with shift + right-click
