Bug Description

So its a little strange. Im running a server on my computer. I had to do this, because simply opening my single player world to LAN caused achievements to not work. When my wife, who is on the same LAN, joins the server, my computers Network Interface Card locks up and i get disconnected from the network. This is only resolved by restarting my computer, i cant even shut/no shut the interface to restore it.

Did this behavior use to work in the previous version?

Didnt have any issue at the beginning, seems to have started after entering age one, but that could be a coincidence.

Steps to Reproduce (for bugs)

1. Launch the sever
   2.Connect to local host
   3.Have someone else connect to the server
