Issue Co-op game crashing when trying to sleep

[Tortoises]

Me and my friend are in the fall of year 2 and upon trying to sleep every time the game crashes and does not save. We could really use some help and I have attached an error log if that might help find a solution. I'm on windows.

Do you have any mods that adds or modify children? Did you delete or uninstall any of those mods?
Try to edit your save file to delete any children and try to load it again.

From your log it looks like you are trying to delete some children NPC's.
It's always good to give as much information as possible when asking for assistance.
