My friend and I are playing on a lan game that I host. We each found brides and he married his first. When I married mine she keeps referring to me by his name when ever I get back home. My friend then had a child with his wife and this prevented me from having a child with mine as the config is limited to one child. My wife somehow thinks I am my friend. We also have the morph mod where we can morph into each other so I thought this may be the issue but I was not morphed as him during any of this or him me.

Known issue with MCA on LAN.
