Issue Game crashes once I leave the farm house (multiplayer)

[nonaneru]

Me and my friend currently having problems with our co-op save, it was working before but now as we're in year 2 of our save, and especially when she married Elliot, I could not leave the farmhouse. At first we thought it was the Elliot mods that she had installed however the game still continues to crash. I assume this is the SpaceCore mod we have? because it recently had an update and it caused some issues when I updated it. Or was it I didn't download a certain mod she has? I hope someone can help us with this?
Here's the error log:
