[0.14.22] crash when starting multiplayer LAN game

[Freaky]

Hi,

the game crashes, when you try to start a multiplayer LAN with 'Verify User Identity' enabled but without an active internet connection.
I wanted to play a game with friends: we had a LAN without internet connectivity. After disabling 'Verify User Identity' on game creation, it worked.

Steps to recreate bug:

0. Disable your internet-connection (but have an IP address to communicate to others on your LAN)
1. start factorio
2. click 'play'
3. click 'Multiplayer'
4. click 'New Game'
5. click 'Generate'
6. disable/uncheck 'Public'
7. enable/check 'Verify User Identity' (should be enabled by default)
8. click 'Play'


Info: This was on the MacOS client. I did not test it on Linux or Windows.

thanks

Freaky

This should be fixed in 0.15.
