Empty sequence error

public static Room? GetRandomRoom(RoomType type)

Just return null or something if the sequence is empty, instead of throwing an error (which disables schematics during generation if spawnlocker causes this error). Also, why ToList() ???

This is fairly easy to fix I'm just too lazy to PR.
