Hey guys, Love the game so far.
I have been faced with an issue.
I have correctly configured my pc's firewall to your ports for game play.
I do not have any other personal firewalls activated.
When I host a game using lan and when my friends that live in the same house using the same router try to go multiplayer/lan/refresh my game client crashes.
This issue doesnt seem to happen if they host just my pc. Which is fine but I would like to get it fixed.

Here is my Latest launch log.

I am having the same problem with my wife. We are on the same network, no firewall, and connecting through a switch. We have totally removed the router from the equation. Why is this happening, guys? This question was asked 2 months ago?

The LAN play problems will be fixed with the next patch.
In the meantime you can work around the problem by using only 1 letter for the "server description" and don't use any mutators.
