The game crashes with the following setting, it is reproducable:
Create Custom Multiplayergame
Map: MegaRandom
Typ: Nomad
Biom: Europa
Map Size: giant
Map Seed: DEADBEEF
Start the game. It will crash on loading screen. Tested multiple times. I guess there is some type of array/buffer overrun when using the hexadecimal value 0xdeadbeef.
