"Sonquest structures" victory condition fails when a player never builds a structure at all.

You can end up with a game that never meets victory condition if one player does not ever manage to build a structure and does not start with one (such as the random nomad maps) when victory condition is "conquest structures"

Probably some sort of logic change that can fix this: maybe victory is also met if all units are dead and no structures are present for that player. Currently it seems that an AI player can have zero units and zero building but still be considered undefeated if they never build a structure with "conquest structures" on.

Maybe this is not the case for a real player and only applies to AI players? Is that possible?
