Giant maps doesn't work anymore in LAN

[JackPotte]

Hello,

We used to play to 0ad 22 in LAN with three colleagues, on giant maps.

However, since we moved to the 23rd version, the giant maps systematically eject the three guests after loading (just before displaying their town hall).

No error are displayed into the host's console.

It occurs:

• on any computer (Ubuntu 16.04 on the four) ;
• with any map ;
• even if the guests join the started game after the bug ;
• it works properly with smaller maps ;
• the giant maps work in solo (including a multiplayer with no human).

Thank you for your attention.

Same as #3700, we'll provide a hotfix and re-release of alpha 23. Not only giant maps.
