Has a server host, which is also a client, and 2 additional clients - all on LAN. The game crashed in about an hour after the start because all memory has become consumed by the game. 8 Gb RAM, shutdown almost everything else but the game.
Looks like a memory leaks to me.
1. Launch the game as a server host 2. Play for about an hour or two 3. Experience game crash caused by a memory leak
